Product Overview

The AD9558/PCBZ is an evaluation board for evaluating the AD9558. The AD9558 provides synchronization for many systems including synchronous Ethernet (SyncE) and synchronous optical networks (SONET/SDH). The AD9558 provides clocking outputs that are directly related in phase and frequency to the selected (active) reference, but with jitter characteristics that are governed by the system clock, the DCO and the output PLL (APLL). The AD9558 generates an output clock synchronised to one of four external input references. The Digital PLL allows for reduction of input time jitter or phase noise associated with the external references. The AD9558 continuously generates a clean (low jitter), valid output clock even when all references have failed by means of a Digitally controlled loop and holdover circuitry.
  • Supports GR-1244 stratum 3 stability in holdover mode
  • Smooth reference switchover with virtually no disturbance on output phase
  • Featured with Telcordia GR-253 jitter generation, transfer and tolerance for SONET/SD
  • AD9558/PCBZ supports ITU-T G.823, G.824, G.825 and G.826
  • ITU-T G.8262 synchronous Ethernet slave clocks
  • Auto/manual holdover and reference switchover
  • Four reference inputs (Single ended or differential)
  • Input reference frequencies of 2KHz to 1250MHz
  • Programmable Digital loop filter covering loop bandwidths from 0.1Hz to 5KHz
  • Programmable 17bit integer and 24bit fractional feedback divider in Digital PL
