Overview

Description

The RC21xxxB (RC21012B and RC21008B) is a member of Renesas's VersaClock® 7 programmable clock generator family. It is intended for high-performance computers, data communications, and industrial applications, designed to be placed immediately adjacent to a PHY, switch, ASIC or FPGA that requires several reference clocks with jitter performance 150fs typical RMS.

Up to 27 configurations reusable across multiple designs may be stored in on-chip One-Time Programmable (OTP) memory or external I2C EEPROM. Redundant input is available for backup and used as a reference clock where needed.

Features

  • 1.8V/2.5V/3.3V flexible power rails
  • Typical 150fs RMS 12kHz - 20MHz phase jitter​
  • 5/8/12 outputs with integrated crystal options
  • 1kHz to 650MHz LVDS/LP-HCSL outputs
  • 1kHz to 200MHz LVCMOS outputs
  • Programmable hardware configuration select-pins
  • PCIe Gen 5/6 ready
  • Space saving packages 4mm x 4mm, 5mm x 5mm, 6mm x 6mm
  • Integrated crystal option for space saving and BOM optimization
