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
