SATURN User Network Interface for J2/E3/T3
PM7347
S/UNI-JET
FEATURES
• Single-chip ATM User Network
Interface (UNI) operating at 44.736
Mbit/s, 34.368 Mb it/s, and 6 .312 Mbit/ s
conforming to ATMF-95-1207R1,
ATMF-94-0406R5, and
AF-PHY-0029.000.
• Provides on-chip DS3, E3 (G.751 and
G.832), and J2 framers. Can be
configured for use solely as a framer.
When configured in framer mode,
gapped transmit and receive clo ck s
can be generated for interfaces that
need access only to payload data bits.
• Supports bypass of the internal
framers and supports connections to
an arbitrary-rate external transmission
system interface up to a rate of 52
Mbit/s. This lets the S/UNI-JET be
used as an ATM cell delineator.
• Implements ATM direct-cell mapping
into T1, DS3, E1, E3, and J2
transmission systems according to
ITU-T Recommendation G.804.
• Provides a SCI-PHY and 50 MHz
UTOPIA Level 2 compatible 8- or
16-bit ATM-PHY Interface.
• Implements the Physical Layer
Convergence Protocol (PLCP) for T1
and DS3 transmission systems
according to the ATM Forum UNI
Specification and ANSI
TA-TSY-000773, TA-TSY-0007 72, and
for E1 and E3 transmission systems
according to ETSI 300-269 and ETSI
300-270.
• Implements the ATM phy sical layer for
broadband ISDN according to ITU-T
Recommendation I.432.
• Uses the PM4341 T1XC, PM6341
E1XC, PM4351 COMET, and framer/
line interface chips for T1 and E1
applications.
• Provides seamless interface to the
VORTEX DSLAM chipset,
®
-ATLAS, and
S/UNI
S/UNI-RCMP-200.
• Provides programmable
pseudo-random test pattern
generation, detection, and analysis
features.
• Provides integral transmit and receive
HDLC controllers with 128-byte FIFO
depths.
• Provides performance monitoring
counters suitable for accumulation
periods up to one second.
• Provides an 8-bit microprocessor
interface for configurati on, co ntrol, an d
status monitoring.
• Provides a standard 5-signal P1149.1
JTAG test por t for boundary scan
board-test purposes.
• Low power 3.3 V CMOS technology
with 5 V-tolerant inputs.
• Available in a high density 256-pin
SBGA package (27 mm by 27 mm).
• Rated for industrial temperature
operation.
APPLICATIONS
• DSLAM Uplinks
• Enterprise ATM/PPP Uplinks
• ATM or Frame Relay Switches,
Multiplexers, and Routers
• DS3/E3/J2 PPP Internet Access
Interfaces
• DS3/E3/J2 Frame Relay Interfaces
