Part Number: LMK00338
Function: 8-Output PCIe Gen1/2/3 Clock Buffer/Level Translator
Package: PLCC 40 Pin Type
Manufacturer: Texas Instruments
The LMK00338 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 IC 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-MHz to 40-MHz Crystal or Single-Ended Clock
2. Two Banks With 4 Differential Outputs Each
(1) HCSL, or Hi-Z (Selectable per Bank)
(2)Additive RMS Phase Jitter for PCIe Gen5 at 100 MHz
