RC22312 Multi-Frequency Clock Synthesizer

The RC22312/RC22308 is an ultra-low phase noise multi-frequency clock synthesizer and digitally controlled oscillator (DCO). This flexible, low-power device outputs clocks with 25fs RMS jitter supporting 112Gbps and 224Gbps SerDes. Applications ▪ Clock synthesis for: * 112Gbps and 224Gbps Se.

RC22312 Features

* ▪ Jitter 25fs RMS, 12kHz to 20MHz with 4MHz HPF ▪ Output frequency range:

* 4kHz to 1GHz for differential outputs

* 4kHz to 250MHz for single-ended outputs ▪ Up to 12 HCSL (AC-LVPECL) or LVDS outputs with independent integer dividers; differential outputs can be configured as two sin
