Description

The Si53315 is an ultra low jitter ten output differential buffer with pin-selectable

output clock signal format and individual OE. The Si53315 features a 2:1 mux,

making it ideal for redundant clocking applications. The Si53315 utilizes Silicon

Laboratories' advanced CMOS technology to fanout clocks from 1 MHz to

1.25 GHz with guaranteed low additive jitter, low skew, and low propagation delay

variability. The Si53315 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.
