S/UNI®-155-STAR

155 Mbit/s ATM and Packet-Over-SONET/SDH Physical Layer Device

PM5352

FEATURES

• Single channel ATM and Packet-over­SONET OC-3c (155 Mbit/s) PHY.

• Provides on-chip clock and data
recovery and clock synthesis.

• Exceeds Bellcore-GR-253 jitter
requirements.

• Inserts and extracts ATM cells or POS
packets into/from SONET SPE.

• Filters and captures Automatic
Protection Switch byes (K1 and K2)
and detects APS byte failure.

• Detects signal degrade and signal
failure thresholds crossing alarms.

• Captures and debounces
synchronization status byte (S1).

• Extracts and inserts the 16 or 64-byte
section trace (J0) and path trace (J1)
messages.

• Extracts and inserts section/line data
communication channels (DCC).

• Provides circuitry to meet holdover,
wander and long term stability.

BLOCK DIAGRAM

• Provides a generic 8-bit
microprocessor interface for device
control and register access.

• Provides standard IEEE 1149.1 JTAG
test port for boundary scan.

ATM

• Implements the ATM Forum User
Network Interface Specification.

• Performs cell payload scrambling and
descrambling.

• Provides a UTOPIA Level 2-compliant
system interface.

• Provides synchronous cell transmit
and receive FIFO buffers.

PACKET-OVER-SONET

• Generic design that supports packet­based protocols like PPP, HDLC and
Frame Relay.

• Implements the PPP over SONET/
SDH specification according to RFC
2615 and 1662 of the IETF.

• Performs flag sequence detection and
insertion.

• Performs CRC-CCITT and CRC-32
FCS generation and validation.

• Performs byte stuffing and destuffing.

• Checks for minimum and maximum
packet lengths.

• Provides a SATURN®-compatible
Packet-over-SONET POS-PHY Level
2 Interface.

PACKAGING

• Low power, 3.3 V CMOS technology.

• Packaged in a 304-pin Ball Grid Array
(BGA) package.

• Industrial temperature range (-40° to
+85°C).

APPLICATIONS

• DSLAM uplinks.

• Access concentrators.

• Layer 3 switches.

• ATM switches.
