[HomeBrew] 60hz time base chip

[Missouri Guy, N0TT]

Hi Gents,

The 8-PIN MM5369 was once used to generate a 60 hz time
base using only a color burst crystal.  Wouldn't you know,
the chip was discontinued some time ago.  I've been
trying to find a replacment that, hopefully, will stay around
for awhile.

Does anyone know of a similar chip that will perform the
same function?

Thanks,
