SEMICONDUCTOR TECHNICAL DATA

3.3 V Zero Delay Buffer

high-speed clocks in PC, workstation, datacom, telecom and other

high-performance applications. The MPC962308 uses an internal PLL and an

external feedback path to lock its low-skew clock output phase to the reference

clock phase, providing virtually zero propagation delay. The input-to-output

skew is guaranteed to be less than 250 ps and output-to-output skew is

guaranteed to be less than 200 ps.

applied to the output for chip and system testing purposes. The MPC962308 PLL enters a power down state when there are no rising

edges on the REF input. During this state, all of the outputs are in tristate and there is less than 50 µA of current draw. The PLL shuts

The MPC962308 has two banks of four outputs each which can be controlled by the select inputs as shown in

Multiple MPC962308 devices can accept and distribute the same input clock throughout the system. In this situation, the difference
