概要

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

    Parametric Table tips

    Tips for Using This Parametric Table:

    • Hide Filters button in header: Collapse or expands filters
    • Column sort buttons in header: Sort Column alphabetically / numerically descending or ascending
    • Reset button in header: Reset all filters to the page default
    • Full Screen button in header: Expand the table to full screen view (user must close out of full screen before they can interact with rest of page)
    • Export button in header: Export the filtered results of the table to an Excel document
    • Filter parts search bar in header: Type to filter table results by part number
    • Hide column button in column headers: Select to hide columns in table
    • AND / OR toggle switches in header: Toggles the logic of this particular filter to be “AND” or “OR” logic for filtering results
    • Multiselect checkboxes at beginning of each row in table: Select these checkboxes to compare products against each other
    • Document icon next to product name in row: View the featured document for this product
