LMK1C1103 - LVCMOS Clock Buffer

Download the LMK1C1103 datasheet PDF. This datasheet also covers the LMK1C1102 variant, as both devices belong to the same lvcmos clock buffer family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.
