Clock buffer and level translator provides high performance, versatility and power efficiency

The Texas Instruments LMK00334-Q1 device is a four-output HCSL fanout buffer intended for data distribution, high-frequency, low-jitter clock, and level translation. The input clock can be chosen from two universal inputs or one crystal input. The selected input clock is issued to two banks of two HCSL outputs and one LVCMOS output. The LVCMOS output has a synchronous enable input for runt-pulse-free operation when enabled or disabled. The device operates from a 3.3V core supply and three independent 3.3V or 2.5V output supplies. The device offers versatility, high performance, and power efficiency, making it an excellent choice for replacing fixed-output buffer devices while increasing timing margin in the system.
