VSC9180
VSC9180 Arapahoe - 2.5G SONET/SDH Backplane Transceiver
FEATURES:
Parallel to Serial Transmit
4Receives 16 or 4-Bit Parallel LVDS/LVPECL Inputs Operating
at 155MHz or 622MHz into Internal FIFO using Source
Synchronous Timing
416-Bit 155MHz Bus or 4-Bit 622MHz Bus is Bit Multiplexed
to Serial 2.5GHz Output
4Retimes Four Serial STS-12/STM-4 Inputs and Deskews up
to +/- 3 Bytes of Skew using the A1/A2 Boundaries
4Byte Interleaves Four Serial STS-12/STM-4 Inputs to Create
an STS-48 like Signal
4Clear Channel Non-SONET/SDH Capability and Support for
Both SONET/SDH and G.709 OTU1 Frames
Serial to Parallel Receive
4Dual 2.5Gb/s Frequency Synchronous Serial CML Inputs
with Onboard Clock and Data Recovery
4Onboard Frame Alignment of Received Signals and Large
Internal FIFO for Tolerance of up to +/-75ns of Serial
Backplane Skew
4Realignment of Incoming Signals Allows Hitless Selection of
Incoming Channel for Maintenance Purposes, and Prevents
Downstream Devices from Having to Reframe in a Failure
Condition
4Hardware Based Switch Over within Receipt of Two or Four Errored
Frame Boundaries
4Loss of Signal, Loss of Alignment, and Loss of Frame Alarm Indication
4Received Frame Pointer Output
4Programmable BER Threshold Monitors Based on B1 Parity Monitoring
of Both Serial Inputs
4Returns 16 or 4-Bit Parallel LVDS Bit De-multiplexed Outputs Operating
at 155MHz or 622MHz with Recovered Bus Clock (Non Interleave Mode)
4Returns Quad STS-12/STM-4 Outputs Operating at 622 Mb/s (Inter-
leave Mode)
4Clear Channel Non-SONET/SDH Capability and Support for Both
SONET/SDH and G.709 OTU1 Frames
Special Features
44-Bit or 16-Bit Parallel Bus Loopback with Output Bus Clock
4Parallel Loopback also Allows Quad STS-12/STM-4 Retime, Realign, and
Loopback Output
4Serial Loopback with Hitless Input Selection and Realignment
4Onboard Discrete CMU and CRU to Accommodate Non-synchronous
TX/RX Applications
