pll 4046

I want to use 4046 phase-locked loop IC.
to generate 12.0MHz (for MPU. clock) from 15,625Hz PAL-B Horizontal Sync.
with phase-locked at rising edge.
(to make an OSD.)

Anyone have the circuit?

pll 4046 application

for PAL application, you'd better use TI's TLC2932,

its speed is higher. the operating speed is:

5V Lock Frequency x1 Output(MHz) 22 to 50

5V Lock Frequency x1/2 Output(MHz) 11 to 25



for detailed application information with

TLC2932,

Added after 3 minutes:


74HC4046 is not as good as TI's TLC2932 and TLC2933,

if you decide to use 74HC4046,

the attched file has many useful information

with 74HC4046.


best regards
