Overview

The RC22514A is a small, low-power timing component designed to be placed immediately adjacent to a PHY, switch, ASIC or FPGA that requires several reference clocks with jitter performance less than 100fs (max). The RC22514A can act as a frequency synthesizer to locally generate the reference clock or as a DCO for frequency margining or OTN clock applications, relying on an internal crystal reference source.

RC22514A - Pin Assignment
  • Jitter below 100fs RMS maximum (10kHz to 20MHz)
  • PLL core consists of fractional-feedback Analog PLL (APLL)
    • APLL frequency independent of input / crystal frequency
    • Operates as a frequency synthesizer or Digitally Controlled Oscillator (DCO)
    • DCO has tuning granularity of < 1ppb 
  • Programmable status output
  • 4 differential / 8 LVCMOS outputs
    • Any frequency from 10MHz to 1GHz (180MHz for LVCMOS)
    • Programmable output buffer supports HCSL (DC-coupled), LVDS/LVPECL/CML (AC-coupled) or two LVCMOS
    • Differential output swing is selectable: 400mV to 800mV
    • Output clock phase individually adjustable in 100ps steps
    • Output Enable input with programmable effect
  • Supports up to 1MHz I2C or up to 20MHz SPI serial processor port
  • Can configure itself automatically after reset via internal customer-definable One-Time Programmable (OTP) memory with up to four different configurations
  • 4 × 4 mm 28-VFQFPN package
