LMK00334 datasheet

Description :

The LMK00334 is a 4-output HCSL 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. The selected input clock is distributed to two banks of 2 HCSL outputs and one LVCMOS output.

The LVCMOS output has a synchronous enable input for runt-pulse-free operation when enabled or disabled. The LMK00334 operates from a 3.3 V core supply and 3 independent 3.3 V/2.5 V output supplies.

The LMK00334 provides high performance, versatility, and power efficiency, making it ideal for replacing fixed-output buffer devices while increasing timing margin in the system.


1. 3:1 Input Multiplexer

   (1) Two Universal Inputs Operate up to 400 MHz and Accept LVPECL, LVDS, CML, SSTL, HSTL, HCSL, or Single-Ended Clocks


   (2) One Crystal Input Accepts a 10- to 40-MHz Crystal or Single-Ended Clock

2. High PSRR: –72 dBc at 156.25 MHz

3. LVCMOS Output With Synchronous Enable Input

4. Pin-Controlled Configuration
