Resources for RC38208
Description
The RC38208 is a high-performance, small form factor, low-power jitter attenuator, multi-frequency clock synthesizer, and digitally controlled oscillator (DCO) designed for critical applications such as 4G/5G RF transceivers and high-speed SerDes. It belongs to Renesas' high-performance FemtoClock™ 3 wireless family. It generates clocks with ultra-low in-band phase noise and spurious signals, achieving jitter below 18fs RMS, making it ideal for 112Gbps and 224Gbps SerDes. The RC38208 can manage up to three synchronization domains, supporting CPRI/eCPRI and synchronization methods like IEEE 1588, Synchronous Ethernet (SyncE), GPI, or GNSS. With up to four frequency domains, it simplifies system clock generation, while integrated LDOs provide superior PSRR, reducing PCB complexity. This makes it an excellent choice for applications such as timing for optical front-end DAC/ADC and DSP, reference clocks for high-speed SerDes, 5G distribution units, and high-performance DCO for PTP-based clocks.
