Overview

Description

The RC32504A 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 a jitter performance of less than 100fs. The RC32504A can act as a frequency synthesizer to locally generate the reference clock, a jitter attenuator to perform local clean-up and/or frequency translation of a centrally-supplied reference, a synchronous Ethernet equipment clock to perform passband filtering and clean-up of network-supplied references or as a DCO for frequency margining or OTN clock applications.

Features

  • Jitter below 100fs RMS (10kHz to 20MHz)
  • Compliant with ITU-T G.8262 for synchronous Ethernet/OTN (EEC/OEC) and ITU-T G.8262.1 for enhanced synchronous Ethernet/OTN (eEEC/eOEC)
  • PLL core consists of fractional-feedback Analog PLL (APLL) which can optionally be steered by a Digital PLL (DPLL)
    • Operates from a 25MHz to 80MHz crystal or XO
    • APLL frequency independent of input/crystal frequency
    • Operates as a frequency synthesizer, jitter attenuator, synchronous equipment slave clock or Digitally Controlled Oscillator (DCO)
    • DPLL loop filter programmable from 0.1Hz to 12kHz
    • DCO has a tuning granularity of < 1ppb
  • Programmable input buffer supports HCSL, LVDS, or two LVCMOS with no external terminations needed
    • Input frequencies: 1MHz to 800MHz (250MHz for LVCMOS)
    • Reference monitor qualifies/disqualifies input clock
  • 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 through internal customer-definable One-Time Programmable (OTP) memory with up to four different configurations
  • 4mm × 4mm 24-VFQFPN package

  3. RC32504 APLL railing high/low after reference loss/restoration

    I'm working on an SDR; I'm using three separate RC32504's to de-jitter clocks from an FPGA for use by an ADC, a DAC, and as a local oscillator reference. Both the reference clocks into the RC32504s are coming from the FPGA (overdriving the crystal input at ...
