GENERAL DESCRIPTION

FEATURES

Cꢀ16 E1, T1, or J1 Short/Long-Haul Line Interface

The DS26334 is a 16-channel short/long-haul line

interface unit (LIU) that supports E1/T1/J1 from a

single 3.3V power supply. A single bill of material can

Units

CꢀIndependent E1, T1 or J1 Selections

support

E1/T1/J1

with

minimum

external

CꢀSoftware-Selectable Transmit and Receive-Side

components. Redundancy is supported through

nonintrusive monitoring, optimal high impedance

modes and configurable 1:1 or 1+1 backup

enhancements. An on-chip synthesizer generates the

E1/T1/J1 clock rates by a single master clock input of

various frequencies. Two clock output references are

also offered. The device is offered in a 256-pin

TEBGA, the smallest package available for a 16-

channel LIU.

Impedance Matching

CꢀCrystal Less Jitter Attenuator

CꢀSelectable Single-Rail and Dual-Rail Mode and

AMI or HDB3/ B8ZS Line Encoding and

Decoding

CꢀDetection and Generation of AIS

CꢀDigital/Analog Loss of Signal Detection as per

T1.231, G.775 and ETSI 300233

CꢀExternal Master Clock can be Multiple of

2.048MHz or 1.544MHz for T1/J1 or E1

Operation. This Clock will be Internally Adapted

for T1 or E1 Usage.

APPLICATIONS

T1 Digital Cross-Connects

ATM and Frame Relay Equipment

Wireless Base Stations

CꢀReceiver Signal Level Indicator from -2.5dB to

-38dB in T1 Mode and –3dB to –43dB in E1

Mode in 2.5dB Increments

ISDN Primary Rate Interface

E1/T1/J1 Multiplexer and Channel Banks

E1/T1/J1 LAN/WAN Routers

CꢀTwo Built-In BERT Testers for Diagnostics

Cꢀ8-Bit Parallel Interface Support for Intel or

Motorola Mode or a 4-Wire Serial Interface
