Overview
Description
The RC32508A regenerates and distributes ultra-low jitter clock outputs and features up to two independent frequency domains that can be either locked to the external reference clock or locked to a free-run crystal or oscillator. Digital PLL (DPLL) support hitless reference switching between references from redundant timing sources. The device supports multiple independent timing channels for clock generation and jitter attenuation for high-speed serial links. Input-to-input, input-to-output, and output-to-output phase skew can all be precisely managed. The device outputs ultra-low jitter clocks that can directly synchronize SerDes running at up to 112Gbps; as well as CPRI/OBSAI, SONET/SDH ADC/DAC. The device is ideal for use in 100G/200G/400G/800G telecom switch line cards, fabric cards, and OTN applications.
