The LMK00338 device is an 8-output PCIe Gen1/Gen2/Gen3 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 4 HCSL outputs and one LVCMOS output. The LVCMOS output has a synchronous enable input for runt-pulse-free operation when enabled or disabled. The LMK00338 operates from a 3.3-V core supply and 3 independent 3.3-V or 2.5-V output supplies.
The LMK00338 provides high performance, versatility, and power efficiency, making it ideal for replacing fixed-output buffer devices while increasing timing margin in the system.
