GENERAL DESCRIPTION

FEATURES

Cꢀ16 E1, T1, or J1 Short-Haul Line Interface Units

CꢀIndependent E1, T1, or J1 selections

CꢀSoftware-Selectable Transmit and Receive-Side

Impedance Matching

The DS26324 is a 16-channel short-haul line

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

single 3.3V power supply. A wide variety of

applications are supported through internal

impedance matching. A single bill of material can

with

minimum

external

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 a 256-pin TEBGA,

the smallest package available for a 16-channel LIU.

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 2.048 or

1.544MHz for T1/J1 or E1 Operation (This clock

will be internally adapted for T1 or E1 Use.)

CꢀReceiver Signal Level Indicator from -2.5dB to

-20dB in 2.5dB Increments

APPLICATIONS

T1 Digital Cross-Connects

CꢀTwo Built-In BERT Testers for Diagnostics

Cꢀ8-Bit Parallel Interface Support for Intel or

Motorola Mode, or 4-Wire Serial Interface

CꢀTransmit Short-Circuit Protection

ATM and Frame Relay Equipment

Wireless Base Stations

ISDN Primary Rate Interface

E1/T1/J1 Multiplexer and Channel Banks

E1/T1/J1 LAN/WAN Routers

CꢀG.772 Nonintrusive Monitoring

CꢀReceive Monitor Mode Handles Combinations of

14dB or 20dB of Resistive Attenuation Along with

12dB to 30dB of Cable Attenuation.

CꢀSpecification Compliance to the Latest T1/E1

Standards—ANSI T1.102, AT&T Pub 62411,

T1.231, T1.403, ITU G.703, G.742, G.775,

G.823, ETSI 300 166, and ETSI 300 233
