Si5342H

Coherent Optical Clocks

The Si5342H uses an External reference and is a 2 input 2 output 100G/400G coherent optical clock. Each of the ouputs can be configured as a high speed output (up to 2.75 GHz) or a general clock output (up to 717.5 HHz) with ultra-low 0.1 ps rms phase jitter. The Si5342H leverages 4th generation DSPLL technology to clean recovered clocks, 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 clock requirements. The single-chip integration of the device enables designers to meet the stringent performance, form-factor and power requirements demanded in 100G/200G/400G line cards and modules. The Si5342H can be quickly and easily configured using ClockBuilder Pro software.
