Description
The Si53301 is an ultra low jitter six output differential buffer with pin-selectable output clock signal format and divider selection. The Si53301 features a 2:1 input mux with glitchless switching, making it ideal for redundant clocking applications. The Si53301 utilizes Silicon Laboratories' advanced CMOS technology to fanout clocks from 1 to 725 MHz with guaranteed low additive jitter, low skew, and low propagation delay variability. The Si53301 features minimal cross-talk and provides superior supply noise rejection, simplifying low jitter clock distribution in noisy environments. Independent core and output bank supply pins provide integrated level translation without the need for external circuitry.
