ESCRIPTION
The ICS85322 is a Dual LVCMOS / LVTTL-to-
Differential 2.5V / 3.3V LVPECL translator and a
HiPerClockS™
member of the HiPerClocks™ family of High Per-
formance Clocks Solutions from ICS. The
ICS85322 has selectable single ended clock in-
puts. The single ended clock input accepts LVCMOS or LVTTL
input levels and translate them to 2.5V / 3.3V LVPECL levels.
The small outline 8-pin SOIC package makes this device ideal
for applications where space, high performance and low power
are important.
