    When I Googled "custom frequency crystals," Google indicated over six
    Yes I considered custom crystals, but I'm holding out of one domestic source
    that someone in the "groups" knows of...

    If we're talking history, when designed were published in electronics
    magazines inevitably the crystal that drove them were 9.54545 (NTSC standard)
    here in USA and Japan, et. al., or 8.86723 (PAL standard) in Europe, et. al.
    These 2 crystals were ubiquitous.

    Now I cant steal one.

    Thanks.

    9.5454MHz is available ($.81 for one at DigiKey).

    You might try here, too:

    If you can hack in another divide-by-2 stage, Mouser and Digi-Key both
    carry 17.734475 MHz crystals, which would give you 8.8672375 MHz.

    If this crystal's only job is to provide a digital logic clock, Mouser
    and Digi-Key also sell programmable crystal oscillators for around $7
    to $10. You tell them what frequency you want and they program it for
    you before shipping. They come in little cans about the size of an
    8-pin or 16-pin DIP IC; you supply power (usually 3.3 V or 5 V) and
    ground and square waves come out.

    I don't have space for 16 pin DIP or such. This is old equipment being
    repaired. Failed crystal. It clocks the video data on a PAL video board (not
    PC type -- proprietary).
     
  7. Israel (or perhaps Palestine).

    Alib*ba has them for 30 pcs for $13. shipped.

    I learned something today. :) I guess if you are clocking something
    digital that doesn't have strict requirements on the clock, they are
    OK. For the OP's application, where the output will eventually be
    analog video, they might not work as well. I was just trying to come
    up with a way to meet his stated and implied requirements (one-off
    repair, desire to get parts from the US.)

    Hello

    I have lots of 4.433MHz in a surface mt 2 pin minican \style. Would donate two or more if wanted. the freq is 1/2 of your desired freq. Made for PAL systems.

    Lesmith Crystals in Canada is where I got some old crystals for a scanner
    (hand me down toy for the kids)
