DS2156

T1/E1/J1 Single-Chip Transceiver

TDM/UTOPIA II Interface

www.maxim-ic.com

GENERAL DESCRIPTION

FEATURES

The DS2156 is a software-selectable T1, E1, or J1

single-chip transceiver (SCT) for short-haul and

long-haul applications. The backplane is user-

configurable for a TDM or UTOPIA II bus interface.

The DS2156 is composed of a line interface unit

CꢀComplete T1/DS1/ISDN-PRI/J1 Transceiver

Functionality

CꢀComplete E1 (CEPT) PCM-30/ISDN-PRI

Transceiver Functionality

CꢀUser-Selectable TDM or UTOPIA II Bus

Interface

(LIU), framer, HDLC controllers, and

UTOPIA/TDM backplane interface, and is controlled

by an 8-bit parallel port configured for Intel or

Motorola bus operations. The DS2156 is pin and

software compatible with the DS2155.

CꢀLong-Haul and Short-Haul Line Interface for

Clock/Data Recovery and Waveshaping

CꢀCMI Coder/Decoder for Optical I/F

CꢀCrystal-Less Jitter Attenuator

CꢀFully Independent Transmit and Receive

Functionality

The LIU is composed of transmit and receive

interfaces and a jitter attenuator. The transmit

interface is responsible for generating the necessary

waveshapes for driving the network and providing

the correct source impedance depending on the type

of media used. T1 waveform generation includes

DSX-1 line buildouts as well as CSU line buildouts

of -7.5dB, -15dB, and -22.5dB. E1 waveform

generation includes G.703 waveshapes for both 75Ω

coax and 120Ω twisted cables. The receive interface

provides network termination and recovers clock and

data from the network.

CꢀDual HDLC Controllers

CꢀProgrammable BERT Generator and Detector

CꢀInternal Software-Selectable Receive and

Transmit-Side Termination Resistors for

75ꢀ/100ꢀ/120ꢀ T1 and E1 Interfaces

CꢀDual Two-Frame Elastic-Store Slip Buffers that

Connect to Asynchronous Backplanes Up to

16.384MHz

Cꢀ16.384MHz, 8.192MHz, 4.096MHz, or

2.048MHz Clock Output Synthesized to

Recovered Network Clock
