... DESCRIPTION ° +85 ° C) The SY87700L is a complete Clock Recovery and Data Retiming integrated circuit for data rates from 32Mbps up to 175Mbps 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 ...

... M9999-111406 hbwhelp@micrel.com or (408) 955-1690 Lock Detect The SY87700L contains a link fault indication circuit which monitors the integrity of the serial data inputs. If the received serial data fails the frequency test, the PLL will be forced to lock to the local reference clock. This will maintain the correct frequency of the recovered clock output under loss of signal or loss of lock conditions ...

... Micrel, Inc. CHARACTERISTICS Performance The SY87700L PLL complies with the jitter specifications proposed for SONET/SDH equipment defined by the Bellcore Specifications: GR-253-CORE, Issue 2, December 1995 and ITU-T Recommendations: G.958 document, when used with differential inputs and outputs. Input Jitter Tolerance Input jitter tolerance is defined as the peak-to-peak amplitude of sinusoidal jitter applied on the input signal that causes an equivalent 1dB optical/electrical power penalty ...
