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.

Hi Michael,
hi Clint,

honestly speaking, I'm not quite sure if this part is really from
Motorola, but it is mentioned in a "consumer and automotive application
note" from Motorola and many other well known mot. ic's are listed in
this note like the famous MC1350 if amp.

Is that really a Moto device? Sounds more like a TFK (telefunken) or
Philips device to me. Of course I could be wrong..

Check the first URL that I posted in reply to the O.P.; you will see
that this device is included in a 1986 Motorola Euro Master Selection
Guide.

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.

Oh, no, predates microcontrollers in TV's for the most part (not by a
lot but at least a little). It probably worked with another chip that
did LED display of channel number and handled pushbuttons for up/down.

The next generation did on-screen display of channel number, that's
where I2C started showing up in at least some tuner/TV's.

Yes, Tim; my second reply to the O.P. referred to the UAA2022, which is
the LED display driver and controller you suspected
