ESCRIPTION
The ICS85222 is a Dual LVCMOS / LVTTL-to-
Differential LVHSTL Translator and a member of
HiPerClockS™
the HiPerClocks™ family of High Performance
Clock Solutions from ICS. The ICS85222 has two
single ended clock inputs. The single ended clock
input accepts LVCMOS or LVTTL input levels and translates
them to LVHSTL levels. The small outline 8-pin SOIC pack-
age makes this device ideal for applications where space,
high performance and low power are important. For optimum
performance, both output pairs need to be terminated, even if
one output pair is unused.
