Si53320-28 Low-Jitter LVPECL Fanout Clock Buffers Data Sheet

PublishTime：2022-03-07

●The Si53320–28 family of LVPECL fanout buffers is ideal for clock/data distribution and redundant clocking applications. These devices feature typical ultra-low jitter char-acteristics of 50 fs and operate over a wide frequency range from dc to 725/1250 MHz. Built-in LDOs deliver high PSRR performance and reduce the need for externa lcomponents, simplifying low-jitter clock distribution in noisy environments.
●The Si53320–28 family is available in multiple configurations, with some versions offer-ing a selectable input clock using a 2:1 input mux. Other features include independent output enable and built-in format translation. These buffers can be paired with the Si534x clocks and Si5xx oscillators to deliver end-to-end clock tree performance.
