Quad T1/E1 Multi-PHY SATURN User Network Interface
FEATURES

microprocessor bus interface for
configuration, control, and status
monitoring.
• Low power, +5 V, CMOS technology.
• Packaged in a 128-pin rectangular
(14 mm by 20 mm) PQFP package.

• Monolithic single-chip quad ATM
Physical Layer User Network Interface
(UNI) operating at 1.544 Mbit/s or
2.048 Mbit/s.
• Integrates a quad full-featured dualmode T1/E1 framer/transmitter for
terminating four duplex 1.544 Mbit/s
DS1 or four duplex 2.048 Mbit/s E1
signals. Recovers T1/E1 clock and
data using a digital phase locked loop
for high jitter tolerance.
• Implements the ATM Forum UNI
Specification V3.1 for DS1 and E1
transmission rates.
• Implements the ATM physical layer for
Broadband ISDN according to ITU-T
Recommendation I.432.
• Implements direct mapping into four T1
or E1 streams according to ITU-T
Recommendation G.804.
• Provides UTOPIA L1-compliant,
UTOPIA L2-compatible ATM-PHY
interface with parity and multi-PHY
control signals.
• Software-compatible with the
PM4341A T1XC, PM6341 E1XC,
PM4351 COMET, PM5346 S/UNI®LITE and PM7345 S/UNI-PDH.
• Application-compatible with the
PM8313 D3MX, PM4314 QDSX, and
PM7323 RCMP-200.
• Provides a generic 8-bit

• Supports CRC multiframe alignment or
the signalling multiframe alignment.
• Declares red and AIS alarms using
Q.516 recommended integration
periods. Provides LOS detection, and
indicates loss of frame alignment
(OOF), loss of signalling, and loss of
CRC multiframe alignment.
• Supports line and path performance
monitoring according to ITU-T
recommendations. Accumulators are
provided for counting CRC-4 errors,
FEBE, frame sync errors, and LCVs.
• Supports reception and transmission
of remote alarm and AIS.
• Provides an HDLC interface for
terminating/generating a datalink.
• Supports the timeslot 16 (64 kbit/s)
datalink which may be used for
common channel signalling, or any
combination of the national bits.

T1 FRAMER/TRANSMITTER
• Supports SF or ESF format signals
using B8ZS or AMI line code.
• Provides Loss Of Signal (LOS)
detection and red, yellow and Alarm
Indication Signal (AIS) alarm detection.
Supports transmission of (AIS) or
yellow alarm signal in all formats.
• Detects violations of the ANSI T1.403
12.5% pulse density rule over a
moving 192-bit window.
• Supports line and path performance
monitoring according to ANSI
specifications. Accumulators are
provided for counting ESF CRC-6
errors, framing bit errors, LCVs, and
LOF, or frame alignment events.
• Provides ESF bit-oriented code
detection/generation, and an HDLC
interface for terminating/generating the
ESF datalink.
• Extracts/inserts the datalink in ESF
mode.

APPLICATIONS
• ATM Switches Supporting DS1 or E1
UNI Ports
• ATM Switches Supporting DS3 or E3
Ports Carrying Multiplexed DS1 or E1
UNI Signals
• ATM Switches Supporting SONET/
SDH Ports Carrying Tributary Mapped
DS1 or E1 UNI Signals
• ATM Customer Premise Equipment
Supporting Multiple DS1 or E1 UNI
Ports

E1 FRAMER/TRANSMITTER
• Supports G.704 2048 kbit/s format
using HDB3 or AMI line coding.
