SI53321-B-GM, Clock Buffer LVPECL 2:10 low-jitter clock buffer (1.25 GHz), 2:1 any-format input

Si5332x Low-Jitter LVPECL Fanout Clock Buffers
Skyworks Solutions Inc. Si5332x Low-Jitter LVPECL Fanout Clock Buffers have up to 10 LVPECL outputs from any-format input and a wide frequency range. The Si5332x is ideal for clock/data distribution and redundant clocking applications. These devices feature typical ultra-low jitter characteristics of 50fs and operate over a wide frequency range from dc to 725/1250MHz. Built-in LDOs deliver high PSRR performance and reduce the need for external components, simplifying low-jitter clock distribution in noisy environments.
