I have this chip:
http://www.gamesx.com/rgbadd/cxa1645.pdf
As explained on page 2, pin 6 needs a "0.4 to 0.5 Vp-p sine wave or
pulse". Also explained on page 12, paragraph #3. The duty cycle must
be 50%.
For PAL operation, the frequency is 4.433619 MHz. I already have a
crystal of such frequency. How do I interface it to the chip?
I'm trying to build this circuit:

But I can't find a 74HCT04 anywhere!
