FEATURES
• Monolithic SONET/SDH PAYLOAD EXTRACTOR/ALIGNER for use in STS-1
   (STM-0/AU3), STS-3 (STM-1/AU3) or STS-3c (STM-1/AU4) interface
   applications, operating at serial interface speeds of up to 155.52 Mbit/s.
• Provides integrated clock recovery and clock synthesis to allow a direct
   interface to optical modules.
• Provides termination for SONET Section and Line, SDH Regenerator Section
   and Multiplexer Section transport overhead, and path overhead of one or
   three STS-1 (STM-0/AU3) paths or a single STS-3c (STM-1/AU4) path.
• Maps one or three STS-1 (STM-0/AU3) payloads or a single STS-3c
   (STM-1/AU4) payload to system timing reference, accommodating
   plesiochronous timing offsets between the references through pointer
   processing.
• Maps a DS3 bit stream into a STS-1 (STM-0/AU3) frame or three DS3 bit
   streams into a STS-3 (STM-1/AU3) frame.
• Provides clear-channel mapping of three 49.536 Mbit/s or 48.384 Mbit/s
   arbitrary data streams into an STS-3 (STM-1/AU3) frame or a single arbitrary
   data stream into an STS-1 (STM-0/AU3) frame. Provides clear-channel
   mapping of a single 149.76 Mbit/s arbitrary data stream into an STS-3c
   (STM-1/AU4) frame.
• Provides versatile datamode interface and optional x^43+1 payload
   scrambling/descrambling to support Packet Over SONET applications.
• Supports line loopback from the line side receive stream to the transmit
   stream and diagnostic loopback from a Telecom ADD bus interface to a
   Telecom DROP bus interface.
• Provides a standard 5 signal P1149.1 JTAG test port for boundary scan board
   test purposes.
• Provides a generic 8-bit microprocessor bus interface for configuration,
   control, and status monitoring.
• Low power +5 Volt CMOS. Device has PECL and TTL compatible inputs and
   TTL outputs.
• 256 pin Super BGA package. Supports Industrial Temperature Range (-40°C
   to 85°C) operation.
