REV. 1.0.1
APPLICATIONS
• SONET/SDH-based Transmission Systems
• Add/Drop Multiplexers
• Cross Connect Equipment
• ATM and Multi-Service Switches, Routers and Switch/Routers
• DSLAMS
• SONET/SDH Test Equipment
• DWDM Termination Equipment
FEATURES
• Quad Channel CDR targeted for SONET STS-12/STS-3/STS-1 and SDH STM-4/STM-1/STM-0 Applications
• Selectable data rate operation between 622.08 Mbps, 155.52 Mbps, or 51.84 Mbps.
• Single-chip fully integrated solution containing quad-channel clock and data recovery (CDR) functions
• Optional flexibility to configure for LVDS or Differential LVPECL High Speed I/O Interface
• Internal 100Ω termination for the high speed LVDS/Differential LVPECL inputs included
• Utilizes reference clock frequency of either 19.44 MHz or 77.76 MHz
• Host mode serial microprocessor interface simplifies monitor and control, including LOS monitoring
• Diagnostics features include LOS monitoring in Host Mode and automatic recovered data mute upon LOS
• Loss of Lock Detect output for each channel
• Permits mixed data rate configuration of the four channels
• Independent power down control of unused channels for lower power operation
