LMK00304 - 3-GHz 4-Output Ultra-Low Additive Jitter Differential Clock Buffer/Level Translator

Description

The LMK00304 is a 3-GHz 4-output differential fanout buffer intended for high-frequency, low-jitter clock/data distribution and level translation.

The input clock can be selected from two universal inputs or one crystal input.

Features

  • 1 3:1 Input Multiplexer.
  • Two Universal Inputs Operate up to 3.1 GHz and Accept LVPECL, LVDS, CML, SSTL, HSTL, HCSL, or Single-Ended Clocks.
  • One Crystal Input Accepts a 10-MHz to 40MHz Crystal or Single-Ended Clock.
  • Two Banks With 2 Differential Outputs Each.
  • LVPECL, LVDS, HCSL, or Hi-Z (Selectable).
  • LVPECL Additive Jitter with LMK03806 Clock Source at 156.25 MHz:.
  • 20 fs RMS (10 kHz to 1 MHz).
  • 51 fs RMS (12 kHz to 20 MHz).
