ICS9DB423 - 4-OUTPUT DIFFERENTIAL BUFFER

Description

The ICS9DB423B is compatible with the Intel DB400Q Differential Buffer Specification.

This buffer provides 4 PCI-Express SRC or 4 QPI clocks.

The ICS9DB423B is driven by a differential output pair from a CK410B+ or CK509B main clock generator.

Features

  • Benefits.
  • Spread spectrum modulation tolerant, 0 to -0.5% down spread and +/- 0.25% center spread.
  • Supports undriven differential outputs in Power Down and DIF_STOP# for modes for power management. Output Features.
  • 4 - 0.7V current-mode differential output pairs.
  • Supports zero delay buffer mode and fanout mode.
  • Bandwidth programming available.
  • 50-133 MHz operation in PLL mode.
  • 33-400 MHz operation in Bypass mode SRC_IN SRC_IN# SPRE.
