FEATURES
• Monolithic SONET/SDH Path Terminating Transceiver that terminates the path
overhead of one or three STS-1 (AU3) paths or a single STS-3c (AU4) path.
• Maps one or three STS-1 (AU3) payloads or a single STS-3c (AU4) payload
to system timing reference, accommodating plesiochronous timing offsets
between the references through pointer processing.
• Operates at 19.44 MHz or 6.48 MHz, processing a duplex 19.44 Mbyte/s or
6.48 Mbyte/s data stream.
• Supports line loopback from line side receive stream to transmit stream and
diagnostic loopback from ADD bus interface to DROP bus interface.
• Operates in conjunction with the PM5343 STXC, or with the PM5312 STTX
and PM5318 SIPO to form a complete physical interface up to photonics.
• Provides a generic 8-bit microprocessor bus interface for configuration,
control, and status monitoring.
• Low power, +5 Volt, CMOS technology, TTL compatible inputs and outputs.
• 160 pin plastic quad flat pack (PQFP) package.
