FEATURES
Single channel ATM and Packet-over-
SONET 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.
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 packet-
based 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.
