LMK00334 datasheet



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 IC operates from a 3.3 V core supply and 3 independent 3.3 V/2.5 V output supplies.

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


1. One crystal input accepts a 10- to 40-MHz crystal or single-ended clock

2. Two banks with two differential outputs each

3. Additive RMS phase jitter for PCIe Gen5 at 100 MH
