155 Mb/s SATURN User Network Interface for WANs

S/UNI-155-PLUS

FEATURES

• Monolithic SATURN®-compatible

Asynchronous Transfer Mode (ATM)
network interface.

• Implements the ATM transmission

convergence (TC) sublayer for ATM
according to ATM Forum specifications
and ITU-T recommendations using the
SONET/SDH 155.52 Mb/s format. Also
implements ATM Forum specified
“Mid-range PHY” rates of 51.52, 25.92
and 12.96 Mb/s.

• Includes on-chip clock recovery and

clock synthesis at all rates. Clocking
can be bypassed for use with external
clock sources. Operates in master or
slave (loop timed) timing modes.

• Provides TTL-compatible inputs and

outputs. Provides differential pseudo-
ECL-compatible serial line side inputs.

• Supports Fiber Optic, Unshielded

Twisted Pair and Shielded interfaces.

• Processes all SONET/SDH UNI

overhead.

• Provides access to section and line

datalinks and all additional transport
and path overhead to allow additional
external processing for full SONET/
SDH Network-Node Interface (NNI)
compliance.

• Provides synchronous 8-bit or 16-bit

SCI-PHY™ system side interface with
4-cell deep FIFO buffers in transmit
and receive paths with parity support.

• Inserts and extracts ATM payloads

using cell delineation.

• Provides a generic 8-bit

microprocessor bus interface for
configuration, control, and status
monitoring.

• Software-compatible with the PM5345

S/UNI-155™, PM5346 S/UNI-155-
LITE™ and the PM5355 S/UNI-622™.

• Provides a standard 5-signal P1149.1

JTAG test port for boundary scan
board test purposes.

• Low power, +5 V CMOS technology.
• Packaged in a 208 pin (28mm x

28mm) PQFP with 0.5mm pin pitch.

• Industrial temperature range operation

(-40

°C to +85°C).

• Counts received cells written into the

receive FIFO, received HCS errored
cells that are discarded, and received
HCS errored cells that are corrected
and passed through the receive FIFO.

TRANSMIT SECTION

• Counts transmit cells read from the

transmit FIFO.

• Inserts a register programmable path

signal label (C2).

• Inserts path B3, path FEBE

indications, line B2, line FEBE
indications, and section B1 to allow
performance monitoring at the far end.

• Optionally inserts the 16- or 64-byte

section trace (J0) sequence and the 16
or 64 byte path trace (J1) sequence
from internal register banks.

• Optionally inserts an externally

generated section user channel (F1),
order wire channels (E1, E2) and the
DCC channels (D1-D3 and D4-D12)
via serial interfaces.

• Optionally inserts path AIS, path RDI,

line AIS, and line RDI.

• Optionally inserts register

programmable APS (K1, K2) and
synchronization status (Z1) bytes.

RECEIVE SECTION

• Filters and captures the automatic

protection switch channel (K1, K2)
bytes in readable registers and detects
APS byte failure.

• Extracts the 16- or 64-byte section

trace (J0) sequence and the 16- or 64-
byte path trace (J1) sequence into
internal register banks.

• Extracts the DCC channels (D1-D3

and D4-D12) for optional external
processing.

• Detects Loss Of Signal (LOS), Out Of

Frame (OOF), Loss Of Frame (LOF),
line Alarm Indication Signal (AIS), line
Remote Defect Indication (RDI-L),
Loss Of Pointer (LOP), path AIS, path
RDI (RDI-P) and Loss Of Cell
Delineation (LCD).

• Counts received section B1 errors, line

B2 errors, line FEBEs, path B3 errors
and path FEBEs for performance
monitoring purposes.

APPLICATIONS

• ATM Switching Systems
• ATM Access Systems
• LAN Switches, Hubs and Routers
• ATM Test Equipment
• SONET or SDH ATM Interfaces
