PRELIMINARY

XRT95L34

OC-12/STM-4, QUAD OC-3/STM-1 POS/ATM FRAMER WITH INTEGRATED CDR’S

MARCH 2002

REV. P1.0.0

• Offers multiple microprocessor compatible interface

- Intel, Motorola, PowerPC, Mips.

GENERAL DESCRIPTION

The XRT95L34 is an OC-12/STM-4, Quad OC-3/

STM-1 POS/ATM Framer with integrated CDR’s. ATM

direct mapping and cell delineation are supported, so

are packets (PPP) over SONET for POS mapping

and frame processing. The XRT95L34 contains an in-

tegral SONET framer which provides framing and er-

ror accumulation in accordance with ANSI/ITU-T

specifications. The configuration of this device is

through internal registers accessible via an 8-bit par-

allel, memory mapped, microprocessor interface.

• Provides 8/16-bit data UTOPIA level II Interface and

POS interface.

• Includes ATM cell or PPP packet Mapping.

• Single +3.3V power supply with +5V input toler-

ance.

SONET TRANSMITTER

• Performs standard OC-3c/STM-1c transmit pro-

cessing.

• Conforms to ITU-T I.432, ANSI T1.105, and

Bellcore-253.

APPLICATIONS

• Edge and WAN ATM Switches

• IP Routers, Packet Switches and Hubs

• Multi-protocol Switches

SONET RECEIVER

• Performs standard STS-12/STS-3c/STM-1c receive

processing.

FEATURES

• Conforms to ITU-T I.432, ANSI T1.105, and

Bellcore-253.

• A single chip solution for ATM UNI and packet over

SONET

HIGH SPEED INTERFACE

• Provides the highest level of protection switching

flexibility for up to 1:14 protected OC-3/STM-1

ports.

• Quad serial OC-3/STM-1 PECL interfaces with inte-

grated CDR, compatible with industry standard

optical modules.

• Provides quad serial OC-3/STM-1 interfaces with

integrated CDR, compatible with industry standard

optical modules.

• Single serial OC-12/STM-4 PECL interface with

integrated CDR, compatible with industry standard

optical modules.

• Provides serial OC-12/STM-4 interfaces with inte-

grated CDR, compatible with industry standard

optical modules.

LOW SPEED INTERFACE

• Complies with ATM forum Utopia Level 2 Specifica-

• Supports the mappings for any standard combina-

tion

tion of STS-12c/AU-4c or STS-3c/AU4.

• Supports 8/16-bit 50MHz transmit and receive

• Provides four 8-bit busses on the line side running

at 19.44 MHz to connect OC-12 framers through a

parallel interface or aggregate four low speed OC-3

devices into an OC-12 line.

interface.

• Provides up to total 16 cell buffers for transmit and

receive.

MICROPROCESSOR INTERFACE

• Supports both SONET and SDH on all interfaces.

SONET/SDH is programmable per interface.

• Supports standard 8-bit micro-controllers with Intel

or Motorola style interfaces.

• Terminates Section Overhead, Line Overhead and

STS-Path Overhead on 4xOC-3, 1xOC-12 inter-

faces. Supports performance monitoring and

alarms required by GR.253, G.707 and ANSI

T1.105.

• ·33 MHz read and write access.

• Provides burst bus transfers.

• Provides DMA controller interface for OAM buffer

interface.

• Provides SONET frame scrambling and de-scram-

bling.

• Separated and multiplexed data/address bus.

• Both write-clear and reset-upon-read for control of

status registers.

• Supports 50 msecond APS by monitoring and filter-

ing K1 and K2 bytes as required by the standards.

• Provides interrupts for alarm processing.

• Offers differential line interfaces.
