B9948L - 1:12 Clock Distribution Buffer

Description

The B9948L is a low-voltage clock distribution buffer with the capability to select either a differential LVPECL or a LVCMOS/ LVTTL compatible input clock.

The two clock sources can be used to provide for a test clock as well as the primary system clock.

Features

  • 160-MHz clock support 2.5V or 3.3V output capability 200-ps maximum output-to-output skew LVPECL or LVCMOS/LVTTL clock input LVCMOS/LVTTL compatible inputs 12 clock outputs: drive up to 24 clock lines Synchronous Output Enable Output Three-state control Pin compatible with MPC948L Industrial temp. range:.
  • 40°C to +85°C 32-pin TQFP package.
