- 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
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.
