Does anyone have this data sheet?

A couple of these chips turned up while I was clearing out a junk box,
apparently the chip is some sort of PLL frequency synth for TVs and
unusual for a UAA prefix its a Motorola part.

TIA.


You're right. Some Googling reveals:
Synthesizer amplifier & driver. Direct tuner driver from 4 Band drivers.
60mA band driver capability. Direct control of the tuners varicap diode.
But so far no datasheet.

Apparently they were used in a Ferguson brand TV, but I don't recall ever
encountering one during my TV repair days, so I probably don't have a
schematic showing one in use either.

Its cropped up on a couple of bulletin boards with other people asking for a
DS, one reply has a link but it turns out to be a UAA2022 - apparently the
2001 is mentioned in the text.
