ICS8344-01

The ICS8344-01 is a low voltage, low skew fanout buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS8344-01 has two selectable clock inputs. The CLK0, nCLK0 and CLK1, nCLK1 pairs can accept most standard differential input levels. The ICS8344-01 is designed to translate any differential signal levels to LVCMOS levels. The low impedance LVCMOS outputs are designed to drive 50 series or parallel terminated transmission lines. The effective fanout can be increased to 48 by utilizing the ability of the outputs to drive two series terminated lines. Redundant clock applications can make use of the dual clock input. The dual clock inputs also facilitate board level testing. The clock enable is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion/deassertion of the clock enable pin. The outputs are driven low when disabled. The ICS8344-01 is characterized at full 3.3V, full 2.5V and mixed 3.3V input and 2.5V output operating supply modes.

Guaranteed output and part-to-part skew characteristics make the ICS8344-01 ideal for those clock distribution applications demanding well defined performance and repeatability.
