Overview

B9949 3.
3V 160-MHz 1:15 Clock Distribution Buffer Features • • • • • • • • • • 160MHz Clock Support LVPECL or LVCMOS/LVTTL Clock Input LVCMOS/LVTTL Compatible Inputs 15 Clock Outputs: Drive up to 30 Clock Lines 1X and 1/2X Configurable Outputs Output Three-state Control 350 ps Maximum Output-to-Output Skew Pin Compatible with MPC949 Industrial Temp.
Range: –40°C to +85°C 52-Pin TQFP Package Description The B9949 is a low-voltage clock distribution buffer with the capability to select either a differential LVPECL or LVCMOS/LVTTL compatible input clocks.
These clock sources can be used to provide for test clocks as well as the primary system clocks.
All other control inputs are LVCMOS/LVTTL compatible.
The 15 outputs are 3.
3V LVCMOS or LVTTL compatible and can drive two series terminated 50Ω transmission lines.
With this capability the B9949 has an effective fan-out of 1:30.
The B9949 is capable of generating 1X and 1/2X signals from a 1X source.
These signals are generated and retimed...
