m o S3076 MULTI-RATE SONET/SDH c CLOCK RECOVERY UNIT . S3076 MULTI-RATE SONET/SDH CLOCK RECOVERY UNIT BiCMOS PECL CLOCK UGENERATOR 4 t FEATURES GENERAL DESCRIPTION e e The function of the S3076 clock recovery unit is to h SiGe BiCMOS technology high speed timing signals for SONET/SDHSwith Bellcore and ITU-T specifica- derive Complies based equipment. The S3076 is implemented using a tions for jitter tolerance, jitter transfer and AMCC’s proven Phase Locked Loop (PLL) technology. atgeneration jitter Figure 1 shows a typical network application. .D On-chip high frequency PLL with internal The S3076 receives an OC-48, OC-24, OC-12, OC-3, loop filter for clock recovery w Fibre Channel or Gigabit Ethernet scrambled NRZ sigclock recovery for: w Supports nal with FEC capability up to 8 bytes per 255-byte (2488.32 Mbps) (with FEC) w OC-48 block and recovers the clock from the data.
