Si5342H-D-GM

The Si5342H is a high-performance 2-input, 2-output coherent optical clock designed for 100G/200G/400G line cards and modules. It utilizes 4th generation DSPLL technology to provide ultra-low jitter (0.1 ps RMS) and any-frequency clock generation up to 2.75 GHz. It features DCO mode for coherent DSP control via a fast SPI interface and integrated MultiSynth fractional synthesis to support eye-diagram monitors, FEC, and MUX/DEMUX requirements. The device utilizes an external frequency reference and eliminates the need for discrete loop filters.
