LMK1C1102 - LVCMOS Clock Buffer

Description

The LMK1C110x is a modular, high-performance, lowskew, general-purpose clock buffer family from Texas Instruments.

The entire family is designed with a modular approach in mind.

Three different fan-out variations, 1:2, 1:3, 1:4, are available.

Features

  • High-performance 1:2, 1:3 or 1:4 LVCMOS clock buffer.
  • Very low output skew < 50 ps.
  • Extremely low additive jitter < 50 fs maximum.
  • 7.5 fs typical at VDD = 3.3 V.
  • 10 fs typical at VDD = 2.5 V.
  • 19.2 fs typical at VDD = 1.8 V.
  • Very low propagation delay < 3 ns.
  • Synchronous output enable.
  • Supply voltage: 3.3 V, 2.5 V, or 1.8 V.
  • 3.3-V tolerant input at all supply voltages.
  • Fail-safe inputs.
  • fm.
