FEATURES
Low-cost, monolithic SATURN
SONET/SDH ATM User Network
Interface (UNI) for category-5 (UTP-5),
Shielded Twisted Pair (STP) and
optical applications.
Implements the ATM Transmission
Convergence (TC) sublayer according
to ATM Forum specifications using the
SONET/SDH 155.52 Mb/s STS- 3c/
STM-1 and 51.84 Mb/s STS-1 formats.
Provides on-chip UTP/STP drivers,
receivers, and line equalizers to allow
direct connection to 155 Mb/s UTP-5
or STP twisted pair wiring facilities
using line coupling transformers.
Provides a selectable UTP/STP or
Pseudo-ECL (PECL) interface to allow
direct connection to Optical Data Links
(ODLs).
Includes clock recovery and clock
synthesis with on-chip loop filters.
Operates in timing master or timing
slave (loop timed) modes.
Frames to SONET/SDH framing bytes
(A1, A2), processes the section and
line Bit Interleaved Parity (B1, B2) and
the Far-End Block Error (Z2) bytes.
Interprets the H1, H2, and H3 payload
pointer bytes.
Processes the SONET path overhead
BIP-8 (B3), signal label (C2) and path
status (G1) bytes.
Inserts and extracts ATM payloads
using ATM cell delineation.
Provides on-chip FIFO buffers in both
transmit and receive paths.
Provides on-chip support for GFC and
XOFF flow control.
Provides a synchronous 8-bit plus
parity SATURN-Compliant Interface for
PHYsical layer devices (SCI-PHYTM)
bus operating at 50 MHz.
Compatible with ATM Forum UTOPIA
interface format.
Provides a generic 8-bit
microprocessor bus interface for
configuration, control, and monitoring.
Provides TTL-compatible inputs and
outputs and differential PECL inputs.
Low power, +5 V CMOS technology.
Packaged in a 128-pin, 14 mm by
20 mm Plastic Quad Flat Pack (PQFP)
with 0.5 mm lead pitch.
