MULTI-PHY USER NETWORK INTERFACE

PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE

FEATURES

• Single chip quad ATM User Network Interface operating at 1.544 Mbit/s or

2.048 Mbit/s.

• Implements the ATM Forum User Network Interface 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 the direct cell mapping into DS1 or E1 transmission systems

according to ITU-T Recommendation G.804.

• Implements (with an external framer device) the direct cell mapping into J2

(6.312 Mbit/s) transmission systems according to ITU-T Recommendation

G.804.

• Integrates a quad full-featured T1/E1 framer/transmitter for terminating four

duplex 1.544 Mbit/s DS-1 signals or four duplex 2.048 Mbit/s E1 signals.

• Integrates a quad ATM cell processor for mapping ATM cells into T1, E1 and

other arbitrary rate streams using HEC (Header Check Sequence Error

Correction) cell delineation.

• Provides Saturn Compatible Interface (SCI-PHYTM) FIFO buffers in both

transmit and receive paths with parity support and Utopia Level 2 compatible

multi-PHY control signals.

• Software compatible with the PM4341A T1XC, PM6341 E1XC, and PM7345

S/UNI-PDH.

• Provides a standard 5 signal P1149.1 JTAG test port for boundary scan board

test purposes.

• Provides a generic 8-bit microprocessor bus interface for configuration,

control, and status monitoring.

• Low power, +5V, CMOS technology

• 128 pin rectangular (14mm x 20mm) PQFP package.
