I have three broken Miranda SER-100D (SDI de-serialisers) on my bench.
They all have the Thompson STV1602A chip within all run very hot and take
0.5A current from  a -5V supply.
However we do have 20 others doing sterling service, so they're not that
bad.

I spoke to someone at Metawave in the UK, who services Alpha-Image kit and
he's changed hundreds of these chips over the past few years. He say's that
the early SPX 1602-01 chip was replaced by the 1602-A and that it had some
different pin functions. He only fits Thompson as he reckons there more
reliable.
You can buy them in the UK from DT Electronics Tel:(0)1203 466500 fax
(0)1203 466501 at 58.35 UKPounds in small quantity.
Today they had 100 in stock.

Now does anybody have any stories about the EQ-45 card on Sony's Digi-Beta,
particularly the GXA82360 chips that cook themselves........
