Si5330x Ultra-Low Additive Jitter Clock Buffers
Skyworks Solutions Inc. Si5330x Ultra-Low Additive Jitter Fanout Clock Buffers offer up to 10 universal outputs from any-format input with a 1MHz to 725MHz wide frequency range. The Si5330x Buffers are designed for clock distribution (1MHz minimum) and redundant clocking applications. The devices feature typical ultra-low jitter characteristics of 50fs. Furthermore, built-in LDOs provide high PSRR performance and reduce external components, simplifying low-jitter clock distribution in noisy environments.
