3.1 GHz fanout buffer with universal input translation
The LMK00301SQE/NOPB is a Texas Instruments fanout buffer, multiplexer, and translator that accepts CML, HCSL, HSTL, LVDS, LVPECL, SSTL, or crystal inputs and delivers HCSL, LVCMOS, LVDS, or LVPECL outputs. It handles up to 3.1 GHz differential signals, making it a fit for high-speed clock distribution in SERDES, base stations, and RF timing chains where signal integrity and low additive jitter matter.
3:11 fanout and industrial temperature range
Three selectable inputs drive eleven outputs — the 3:1 input mux lets you switch between reference clocks or a local crystal oscillator without an external mux. Supply voltage is 3.15V to 3.45V, a tight window that keeps the internal PLL and output drivers in their linear region.
