The Freescale Semiconductor, Inc. MPC9443 is a 2.5 V and 3.3 V compatible 1:16

clock distribution buffer designed for low-voltage high-performance telecom, networking

and computing applications. The device supports 3.3 V, 2.5 V and dual supply voltage

(mixed-voltage) applications. The MPC9443 offers 16 low-skew outputs which are divided

into 4 individually configurable banks. Each output bank can be individually supplied by

2.5 V or 3.3 V, individually set to run at 1X or 1/2X of the input clock frequency or be

disabled (logic low output state). Two selectable LVPECL compatible inputs support

differential clock distribution systems. In addition, one selectable LVCMOS input is

provided for LVCMOS clock distribution systems. The MPC9443 is specified for the

extended temperature range of –40 to +85°C.
