 description:  250mhz410/11

the sp8647 is an ecl variable modulus divider, with
ecl10k and ttl/cmos compatible outputs. it divides by 10
when either of the ecl control inputs, pe1 or pe2, is in the high
state and by 11 when both are low (or open circuit).
the two clock inputs are interchangeable and either will act
as a clock inhibit when connected to an ecl high level.
normally, one input is left open circuit and the other is accoupled,
with externally applied bias.
