Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & munity LMK00804B SNAS642A – JUNE 2014 – REVISED JULY 2014 LMK00804B Low Skew, 1-to-4 Multiplexed Differential/LVCMOS-to-LVCMOS/TTL Fanout Buffer.

General Description

The LMK00804B is a low skew, high performance clock fanout buffer which can distribute up to four LVCMOS/LVTTL outputs (3.3-V, 2.5-V, 1.8-V, or 1.5V levels) from one of two selectable inputs, which can accept differential or single-ended inputs.

The clock enable input is synchronized internally to eliminate runt or glitch pulses on the outputs when the clock enable terminal is asserted or de-asserted.

The outputs are held in logic low state when the clock is disabled.

Key Features

  • 1 Four LVCMOS/LVTTL Outputs with 7 Ω Output Impedance.
  • Additive Jitter: 0.04 ps RMS (typ) @ 125 MHz.

  • Output Frequency: 350 MHz (max).
  • Output Skew: 35 ps (max).
  • Part-to-Part Skew: 700 ps (max).
  • Two Selectable Inputs.
  • CLK, nCLK Pair Accepts LVPECL, LVDS, HCSL, SSTL, LVHSTL, or LVCMOS/LVTTL.
  • LVCMOS_CLK Accepts LVCMOS/LVTTL.
  • Synchronous Clock Enable.
  • Co.
