Hi Tim,

I have no possibility to find out the pinout from a tuner as I have just
a hand full of this mysterious ic's without a documentation on them.

So at least I will have to blow some of them to find out the pin out
with a bit of luck if it is not a I2C device.

Hi OMs/OPs and NG readers,

I'm looking for a pinout and/or data sheet of a old Motorola ic named

UAA2001

should be a pll synthesizer for TV tuners.

I always thought that was a Toshiba part.

80's era TV and VCR tuners are most interesting, IMHO, used as the tin-
can modules. If the TV is still functional you can usually figure out
the header connector functions with a voltmeter or even a logic probe
- no need to dink around with pinouts.

Do modern TV's still have the tin-can tuner modules, or is it more
highly integrated these days? Of course a modern TV isn't an analog TV
anymore either...geeze, it's been at least a decade since I tore into
broken TV's and VCR's for parts, I gotta start doing it again! If
we're lucky there will be a huge flood of older analog TV's for
scavenging soon.
