Default uPDxxxxx chips datasheets (camcorder, vcr, etc)

Does anyone have a repository of datasheets or at least valid signal
descriptions for uPD series chips used in Matsu****a (Panasonic)
camcorders, vcrs, etc.?

Currently I am seeking data on the uPD9313G or uPD9313GB video sync
generator; the pin descriptions for this part, on a schematic in
a camcorder service manual, are incorrect, as evidenced by a block
diagram which labels the pins entirely differently (and also by
common sense).

The chip is totally unlike the LM1882 or 74ACT715 parts for which data
is available.

This particular manual contains no descriptions of operation of the
device and many pins connect to downstream proprietary devices so
deducing their function in context is unlikely. If one is to believe
the pin labeling in the block diagram however, a small number of
pins have standard outputs like Vertical and Horizontal Drive,
Blanking, Composite Sync, Clamp Pulse, but other abbreviations are
cryptic and to me unfamiliar. Scoping other output pins could yield
clues, but the inputs and programming pins are the mystery.

Unless this chip was produced for just one model of camcorder, it will
have some standard functions and inputs; I hope to learn how to genlock
it.
