SY87700

In Production

The SY87700AL is a complete clock recovery and data retiming integrated circuit for data rates from 32Mbps up to  208Mbps  NRZ.  The  device  is  ideally  suited  for  SONET/SDH/ATM applications and other high-speed data transmission systems. Clock  recovery  and  data  retiming  is  performed  by  synchronizing the on-chip VCO directly to the incoming data stream. The VCO center frequency is controlled by the reference clock frequency and the selected divide ratio. On-chip clock generation is performed through the use ...

    • Description

    The SY87700AL is a complete clock recovery and data retiming integrated circuit for data rates from 32Mbps up to  208Mbps  NRZ.  The  device  is  ideally  suited  for  SONET/SDH/ATM applications and other high-speed data transmission systems. Clock  recovery  and  data  retiming  is  performed  by  synchronizing the on-chip VCO directly to the incoming data stream. The VCO center frequency is controlled by the reference clock frequency and the selected divide ratio. On-chip clock generation is performed through the use of a frequency multiplier PLL with a byte rate source as reference. The SY87700AL also includes a link fault detection circuit.
