LMK00301 - 3-GHz, 10-Output Differential Fanout Buffer / Level Translator - 通用（可编程） - 时钟缓冲器 - TI公司（Texas Instruments，德州仪器）
The LMK00301 is a 3-GHz, 10-output differential 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 5 differential outputs and one LVCMOS output. Both differential output banks can be independently configured as LVPECL, LVDS, or HCSL drivers, or disabled. The LVCMOS output has a synchronous enable input for runt-pulse-free operation when enabled or disabled. The LMK00301 operates from a 3.3 V core supply and 3 independent 3.3 V/2.5 V output supplies.
The LMK00301 provides high performance, versatility, and power efficiency, making it ideal for replacing fixed-output buffer devices while increasing timing margin in the system.
