Thanks very much Bob, Tinco and Andrew.
It makes completely sense with what I was able to dig out.
The background to the whole story is that I was looking for an analog
multiplier to separate the cosine component from a sine+cosine signal
in the range 100kZh-1MHz by means of a synchronous demodulator.
Looking for a suitable chip (everything below 500MHz bandwidth seems
to be obsolete nowadays...) I found the MC1595 in our storage, but the
web only gave back information about the MC1495 and some vague hints
that the two chips might be compatible...
Thanks alot,
Uwe.
