Thank you.

SLVS-EC is going to Very Very Interesting and challenging, First you can't use Crosslink-NX as it does not have an SerDes capable of handling clock Recovery. As you have correctly Suggested CertusPro-NX has every thing. But one more challenge i have is I don't really know many camera sensors with SLVS-EC, I know and Hav IMX294 which can generator SLVS-EC, Do you know any other Cheap sensor may that supprts SLVS-EC?

@circuitvalley Hey, thank you for replying. I know no cheap ones, but I know some that are Sony too. IMX387 but expensive at (SLVS-EC 8 lanes) 16.78 MP 61FPS 8-bit and 56FPS 10-bit. A better option is IMX432 that is cheaper at (SLVS-EC 1 lane) 1.76 MP 75FPS 12-bit. I've done research about these two image sensors for months, but very few outcomes produced. I was thinking about adapting your IMX477 CSI CrossLink with these two image sensors, maybe something similar would be applied. Moreover, how do you find reference designs for IMX477? I tried to find any, for that and my SLVS image sensors selection, but it's so hard I get none. Unfortunately the datasheet is not telling much, because it typically has only 2 pages. I'm really into this camera module thing, because it relates to my academic project in EC engineering.

@@sammtanX Datasheets are not normally available in public domain. It appears to be that sensors manufacturers do not really prefer to have sensor information in public domain. I almost always able to get sensor information from sensor/camera distributors by showing them interest in there product. If you can't get info from them or google search I sugget Search on Chinese sites in chinese there many people just publish on Chinese forums all the time. Usage of sensor can always taken from Linux repo. When it come to Reference designs. Almost every Sony Sensor has Two documents. One it data sheet, Which can give sensor's capability and PCB footprint this information is enough to design a PCB. every sensor also has one more document its called Support Package. it has more detailed info about power, Test and other stuff. Just searching on Chinese site give lot of info. one thing always to keep watch Many sony sensors have same footprint so if you have info about one you can just use that info. If you are really desperate you just buy one Camera with that particular sensor and copy everything, Power supply, Land pattern , I2C commands. and you are done. I have done that many time successfully.

Last two volts are Regulated in the Linear Section. Switching regulator always regulate a little higher than then Output voltage and Final regulation is done by Linear state Each channel has a PIC microcontroller controlling DACs to set Voltages in the Linear Regulation section.

​@@circuitvalleywhat is used in the linear section? Do you have a part number? Plus where is the 3.3v for each channel pic controller coming from? It cannot be provided by the transformer that gets pwm controlled by the puc32 of course... so there is a seperate decoupled power supply for the 3.3? Very very nice power supplies! Now I understand why you have 3 of them :)

@@therealspixycat Linear Regulation is done with Opamps and a Pass transistor. It does not uses a off the shelf Linear Regulator. Primary Switching Supply delivers only one Supply 48V nothing else. These supplies are Pretty nice, easy to use.

@@circuitvalley ahaaaa just to keep the voltage drop over the final transistor to a minimum by adjusting the input voltage: very smart! A combination of modern and very old technology.

@circuitvalley the dissipation of that final transistor is very low so it will or can't get the full 48v? The pic regulates the pwm of its own mosfet on the primary side of that 48v transformer via an opto coupler?

Price shot up after Video was listed on Hackaday.

Thank you For your Info.

@@circuitvalley oh by the way, the pulsing is probably just to conserve energy.

Soldering Video is also coming, Thank you

Yes They can be used in Permanent setup as well.

How does ground work on this power supply? When I measure plus to minus I get the voltage dialed-in, but when I measure plus to ground I get about 2/3rds the voltage set. Is the ground common? Floating? Confused.

@@mootzeroni I have just looked at schematic, Output is Floating with GND. Voltage you see will be due to parasitic capacitance in the Transformer.

@ this is very helpful. Thank you so much. I’m now using a pair of these (only mine has a meter with wiper) to provide a highly regulated +/-15vdc for a stereo phono preamp. Overkill, I’m sure but looks kinda cool and sounds great.

Thank you for your Comments, Until unless you are a big corporation, I don't think anyone going to pay list price. On secondhand market things have really different price.

That is a good point. I would try to make PCIe basics video. Thank you for your kind words and nice suggestions.

Thank you

Digital microscope at lower end are that good of performance. Second they always have lag. I always preferred analog optics. now with mantis elite there is nothing better available.

@@circuitvalley well for 100-300$ you can get good ones with a Sony IMX sensor and at least 60FPS. I use an HDMI microscope for ages and the soldering distance is around 30cm. Secondly I use a traditional stereo microscope, I also like that one.

I am just a basic Engineer with CS education.

Thanks for watching

Thank you.

Yes it has 8Ghz Bandwidth, with 20Ghz sampling rate. Yes it can just look at radio signals in time domain.

I made some arrangements to get my hands on this scope

Thank you

Thank you, There will more stuff coming soon.

Welcome aboard!

Thanks for liking

Thank you as well

I am Thankful for your comment. I don't really know if my own voice is pleasing. I am also have some echo problems in my LAB. So i experimented with TTS. I hope to find a solution soon.

Yes you are absolutely right R&S is very very Intuitive. Very modern and elegant interface.

I have a project with IM294, it is still in process of getting published.

Yes its very very expensive, Lens them self are very expensive. But i got it used and Lens also used.

Yes

You are absolutely correct Oscilloscope have small screen. USB Logic analyzer though very very cheap and offer really great value and also grate software. USB Logic Analyzer with 1GS/s will not be very cost effective. These videos are just ment to show to how to things are done. I am thankful for your time and consideration.

a dslogic u3pro32 with 1gs/s cost around 400 bucks, just the next step up to 2 or even 5gs/s adds like two zeros to the price tag

Me too!

Yes CAN Video is in pipeline it be coming out very very soon. Maybe just this weekend.

@schoolpost2009 Here is your CAN Bus Video kzbin.info/www/bejne/rXeQc6Nprqt3q6c

I am working on it.

Glad you Liked it

@bambamfpv1102 Thank you for your suggestion, I have a Patreon www.patreon.com/circuitvalley

@@circuitvalley Thank you. This was a good start to the series.

I have HMC8043 From Rohde and Schwartz

I am working on it.

A video will be coming soon.

Thank you

Glad you enjoyed it!

@SingularityofPower , You buy from reseller in your area. Framos is one in Germany, There is seller in USA as well.

Not really, This is how I solder many many board. I know people personally how do medium prototype run like this. Its very very fast. Now to control the components first you have the wire itself and second surface tension of both of ends soldering at time automatically align itself. if you practice it works really well.

@@circuitvalley Keep on doing it. I just can't put a tiny SMT device on the tip of the iron. You are decreasing the life of the component. Also, you cannot do this on any SMT LED period... (devices smaller than 0603???).

It’s probably a technique that requires practice. You might want to try it for awhile before stating that it’s useless. He clearly demonstrated doing it in the video so he managed to control the device on the tip of the iron. So it can be done.

@@totallyfrozen Of course it can be done. He did it in the video. You go ahead and use it. I don't have to try it to know it is not good for the part having handled soldering iron 25+ years. I guess you'll learn when tolerances are tight and frequencies are high. Keep going... it won't affect my wallet. Hey, kick it up to 350 C while you are at it. It wets much better... hahahaha

​@@thekaduu Some people may have a agenda just to criticize , That is totally understandable, but with there agenda they miss the facts. I suggested , Using solder wire itself you can have some control over the components and its orientations. Watch carefully. I also suggested be quick. to prevent any damage to heat. But please try and understand. Soldering one side and then soldering other side may also cause damage.

Thank you, I much appreciate your feedback on every single video .

@@circuitvalley Thanks for making these nice videos :)

Thank you, I appreciate

I think either EEVBlog or The Signal Path has a tear down of one of them.

Yes, I just checked. Dave has a teardown of a 2005 from 10 years ago. "EEVblog #649 - Power Designs 2005 PSU Teardown"

Teardown would be good but There is not really much to see to understand it, There only few very precise resistor on the rotary Switches . If you want to understand schematic is available on the internet. It has a error amplifier and few resistor with a drive transistor. Error Amplifier transistor are in a small temperature controlled enclosure.

Thank you

Exactly, Some how They just never lose it.

@@circuitvalley They really are amazing. I think I got mine on eBay about 5 or 6 years ago. I'm sure the price of them has shot through the roof now.

You’re welcome 😊
