MPC9443  
2.5 V and 3.3 V LVCMOS Clock  
Fanout Buffer  
The 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.

Functional Description  
The MPC9443 is a full static design supporting clock frequencies up to 350 MHz. The signals are generated and retimed on-chip  
to ensure minimal skew between the four output banks.  
Two independent LVPECL compatible clock inputs are available. This feature supports redundant differential clock sources.  
In addition, the MPC9443 supports single-ended LVCMOS clock distribution systems. Each of the four output banks can be individu-  
ally supplied by 2.5 V or 3.3 V, supporting mixed voltage applications. The FSELx pins choose between division of the input reference  
frequency by one or two. The frequency divider can be set individually for each output bank. The MPC9443 output banks are in  
high-impedance state by deasserting the OEN pins. Asserting OEN will the enable output banks. Please see Table 4. Output  
High-Impedance Control (OEN) for details. The outputs can be synchronously stopped (logic low state). The outputs provide  
LVCMOS compatible levels with the capability to drive terminated 50 Ω transmission lines. For series terminated transmission lines,  
each of the MPC9443 outputs can drive one or two traces giving the devices an effective fanout of 1:32 at VCC = 3.3 V. The device is  
packaged in a 7x7 mm2 48-lead LQFP package.
