VSC9180

VSC9180 Arapahoe - 2.5G SONET/SDH Backplane Transceiver

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)

F E A T U R E S :

4Clear Channel Non-SONET/SDH Capability and Support for Both

Parallel to Serial Transmit

SONET/SDH and G.709 OTU1 Frames

4Receives 16 or 4-Bit Parallel LVDS/LVPECL Inputs Operating

at 155MHz or 622MHz into Internal FIFO using Source

Synchronous Timing

Special Features

44-Bit or 16-Bit Parallel Bus Loopback with Output Bus Clock

416-Bit 155MHz Bus or 4-Bit 622MHz Bus is Bit Multiplexed

4Parallel Loopback also Allows Quad STS-12/STM-4 Retime, Realign, and

to Serial 2.5GHz Output

Loopback Output

4Retimes Four Serial STS-12/STM-4 Inputs and Deskews up

4Serial Loopback with Hitless Input Selection and Realignment

to +/- 3 Bytes of Skew using the A1/A2 Boundaries

4Onboard Discrete CMU and CRU to Accommodate Non-synchronous

4Byte Interleaves Four Serial STS-12/STM-4 Inputs to Create

an STS-48 like Signal

TX/RX Applications

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
