Overview
Description
The RC223xxA (RC22308A and RC22312A) is a high-performance, small form factor, low-power clock generator, belonging to Renesas' high-performance FemtoClock™ 3 family. It supports ultra-low jitter clocks for 100G/200G/400G/800G SerDes data center equipment reference clock applications. It also comes with three Fractional Output Dividers (FOD), and it can support up to four frequency domains.
Features
- Ultra-low jitter performance: Achieve exceptional precision with jitter performance as low as 50fs at 312.5MHz within a wide 12kHz to 20MHz integration range in jitter attenuator mode
- Versatile power supply options: Operate the device with ease using a single 1.8V power supply while ensuring compatibility with a 3.3V level interface at SCL/SDA pin if the VDDD33_SERIAL is 3.3V
- DCO mode support: Leverage the benefits of the DCO mode for added flexibility and efficiency
- Configurable startup options: Load configurations at startup effortlessly with the support of an external EEPROM, streamlining your setup process
- Flexible communication interfaces: Choose between SPI or I2C communication protocols for seamless device integration
- Multiple OTP configurations: Benefit from up to four OTP configurations for startup

How can I achieve the best performance for the FemtoClock 3 Wireless in regards to phase noise with the lowest crosstalk.
... and RC32308 (FC3) or the RC38108, RC38208, RC38112 and RC38312 (FC3W). There are also FC3 devices that are only frequency clock synthesizers, such as the RC22308 and RC22312 (FC3). The jitter attenuators (JA) consist of inputs, a DPLL to perform the filtering, an APLL, and outputs. The synthesizers (Synth) do ...
