i noticed the .pdf file for the cxa1145 was missing some information.  i dont know if its worth mentioning but its missing the application notes that show how to get Y,C output for s-vhs.  it requires a second cxa1145 chip, a delay line, band pass filter, two variable resistors, ect.

anyone interested in this?

I don't have the info you're looking for (Use a CXA1645 instead, it has real svideo) but I can tell you it's not s-vhs (that's a video tape), it's s-video.  

viletim!

If it's by sony then yeah, I'd like to see it. It's in japanese isn't it?

my above post could have been written better, sorry about the confusion.

its by sony and its in english.  i would have scanned it into my computer and posted it, but i dont have a scanner.  so i thought id ask if it was something people might be interested in...before i went to the trouble.

as far as whats written, there isnt much so ill just write it out.  


Application Note CAVO2
NTSC/PAL Encoder Y,C Interface

RGB encoder - CXA1145P/M can provide Y, C output.  The following is the circuit diagram to apply this output.  S-VHS requires 75ohm drive capability for Y, C output.  Output level should be adjusted with 1k ohm potentiometers.  Recommended parts are the following, and available from TOKO America  (Telephone: 708/297-0070)



3.58MHz Band Pass Filter        H286BAIS-6276DCD
4.43MHz Band Pass Filter        H286BAIS-4963DCD
Delay Line                             H288LSMS-3245PKD
