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 100 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
Meets Telcordia, ANSI and ITU-T G.783 and G.825 SDH jitter requirements including T1.105.03 - 2002
SONET Jitter Tolerance specification, and GR-253 CORE, GR-253 ILR SONET Jitter specifications.
Complies with ANSI/TIA/EIA-644 and IEEE P1596.3 3.3V LVDS standard, 3.3V Differential LVPECL, and
JESD 8-B LVTTL and LVCMOS standard.
Operates with dual power supply of 1.8V core and 3.3V IO supply
90mW LVDS/ 350mW Differential LVPECL per channel Typical Power Dissipation
Package: 14 x 14 x 1.4 mm 128-pin LQFP
