You can get up to 5 samples of the lm1881 directly from the manufactor. You should check on the website. It only depends on the quantity you need. They'll deliver it in few day by Fedex or equivalent and the all for free.
hello i am in need of video sync separator but i m unable to get it from gujarat. may be this ic is now out or order can anyone give proper option on exchange of lm1881, which is easily available.
lm1881 is not a good solution. Better to use Elantec sync separator. You can find the complete schematic in the Elantec datasheet.
My senior design project requires me to design a frame grabber that captures still images from a ccd video camera. (greyscale, nothing fancy, low quality image) I am thinking about using lm1881 and philips tda8708a to digitize the analog video signal, then feed this 8 bit data to a fifo to das16 and finally to the computer. I have a budget of 15
Hi , Maybe this application note for lm1881 can help you. Good Luck.
use lm1881 sync. separator
If you need to detect/extact Hsync and Vsync signals there are inexpensive ICs which can do this for you: lm1881, EL4581, GS4881 - to name just a few .. Regards, IanP
lm1881 is the equivalent to GS4881 .. Attached is something to think about .. Regards, IanP
Hi all, I need to build a RGB Sync on Green to VGA Converter. Was thinking to use a lm1881. I have a SIEMENS 605NC with RGB video output. The VSync and HSync signals goes togheter with GREEN analog signal and I want to use a NEC MultiSync VGA monitor. Is it possible? Regards, Fernando
lm1881 generates composite sync, vertical sync, odd/even and back porch sinals. The back porch is very different from composite blanking signal. How can we use back porch instead of composite blanking?
Hello friends i design a cross bar Project In which, i have edit PAL Video signal and make one horizontal and one vertical black line on CCTV Monitor My hardware is --PIC 18F4431, 20MHz Crystal --lm1881 My Horizontal line is OK But my vertical line is fluctuated, i use polling programming to detect horizontal sync; what is ba
There is an alternative way. The color decoder is locked to a burst of 3.58MHz sent during the horizontal blanking period. The burst is required for the decoder to operate and if missing, the TV/monitor will disable it's color decoder. If you strip out the sync signals using an lm1881 or similar device which is very inexpensive, and use the blank
Look lm1881
