FANOUT BUFFER
General Description
The ICS8312 is a low skew, 1-to-12 LVCMOS/
ICS LVTTL Fanout Buffer and a member of the
HiPerClockS™ HiPerClockS™ family of High Performance Clock
Solutions from IDT. The ICS8312 single-ended clock
input accepts LVCMOS or LVTTL input levels. The
low impedance LVCMOS outputs are designed to drive 50Ω series
or parallel terminated transmission lines. The effective fanout can
be increased from 12 to 24 by utilizing the ability of the outputs to
drive two series terminated lines.
The ICS8312 is characterized at full 3.3V, 2.5V, and 1.8V, mixed
3.3V/2.5V, 3.3V/1.8V and 2.5V/1.8V output operating supply
modes. Guaranteed output and part-to-part skew characteristics
along with the 1.8V output capabilities makes the ICS8312 ideal
for high performance, single ended applications that also require a
limited output voltage.
