FEATURES

• Single chip quad ATM and POS User-

Network Interface operating at

622 Mbit/s.

• Implements the ATM Forum User

Network Interface Specification and

the ATM physical layer for Broadband

ISDN according to CCITT

Recommendation I.432.

• Implements the Point-to-Point Protocol

(PPP) over SONET/SDH specification

according to RFC 2615(1619)/1662 of

the PPP Working Group of the Internet

Engineering Task Force (IETF).

• Processes four bit-serial 622 Mbit/s

STS-12c (STM-4-4c) data streams

with on-chip clock and data recovery

and clock synthesis.

• Complies with Bellcore GR-253-CORE

jitter tolerance, jitter transfer and

intrinsic jitter criteria.

• Each channel provides termination for

SONET Section, Line and Path

overhead or SDH Regenerator

Section, Multiplexer Section and High

Order Path overhead.

• Provides UTOPIA Level 3 32-bit wide

System Interface (clocked up to

104 MHz) with parity support for ATM

applications.

• Provides SATURN POS-PHY

Level 3™ 32-bit System Interface

(clocked up to 104 MHz) for Packet

over SONET (POS), or ATM

applications.

• Supports line loopback from the line

side receive stream to the transmit

stream and diagnostic loopback from

the line side transmit stream to the line

side receive stream interface.

• Provides support for automatic

protection switching including a bi-

directional 4-bit PECL 622 MHz port

for external APS with mate device.

• Built-in APS cross-connect for internal

and external 1+1 and 1:n protection

switching.

• Provides a standard five signal IEEE

1149.1 JTAG test port for boundary

scan board test purposes.

• Provides a generic 16-bit

microprocessor bus interface for

configuration, control, and status

monitoring.

• Low power 2.5 V CMOS core logic with

3.3 V CMOS/TTL compatible digital

inputs and digital outputs. PECL inputs

and outputs are 3.3 V compatible.

• Industrial temperature range (-40° C to

+85° C).

• 520 pin SBGA package.

• Pin and software compatible with

PM5382 S/UNI-16x155.

APPLICATIONS

• ATM and Multiservice Switches,

Routers, and Switch/Routers.

• SONET/SDH Add/Drop Multiplexers

with data processing capabilities

• Uplink Cards.

• SONET/SDH ATM/POS Test

Equipment.
