Description

The RC323xxA (RC32308A and RC32312A) is a high-performance, small form factor, low-power jitter attenuator with network synchronization capabilities, belonging to Renesas' high-performance FemtoClock™ 3 family. It supports Synchronous Ethernet (SyncE) for network-based synchronization and outputs ultra-low jitter clocks that can directly synchronize SerDes running at up to 112G pulse amplitude modulation (PAM), as well as CPRI/OBSAI, SONET/SDH, and ADC/DAC. This makes it an excellent choice for 100G/200G/400G/800G telecom switch line cards, fabric cards, wireline infrastructure, data center equipment, and instrumentation applications. It allows locking to external reference clocks or free-run crystals/oscillators and supports hitless reference switching between redundant timing sources. The device is versatile, supporting timing channels for SyncE clock generation, jitter attenuation, and precise phase skew management for input-to-input, input-to-output, and output-to-output configurations.
