GENERAL DESCRIPTION

FEATURES

CꢀEight Complete T1, E1, or J1 Long-Haul/Short-

The DS26528 is a single-chip 8-port framer and line

interface unit (LIU) combination for T1, E1, and J1

applications. Each port is independently configurable,

supporting both long-haul and short-haul lines.

Haul Transceivers (LIU plus Framer)

CꢀIndependent T1, E1, or J1 Selections for Each

Transceiver

CꢀInternal Software-Selectable Transmit- and

Receive-Side Termination for 100ꢀ T1 Twisted

Pair, 110ꢀ J1 Twisted Pair, 120ꢀ E1 Twisted

Pair, and 75ꢀ E1 Coaxial Applications

APPLICATIONS

Routers

Channel Service Units (CSUs)

Data Service Units (DSUs)

Muxes

Switches

Channel Banks

T1/E1 Test Equipment

CꢀCrystal-Less Jitter Attenuators can be Selected

for Transmit or Receive Path. The Jitter

Attenuator meets ETSI CTR 12/13, ITU G.736,

G.742, G.823, and AT&T PUB 62411.

CꢀExternal Master Clock can be Multiple of

2.048MHz or 1.544MHz for T1/J1 or E1

operation. This Clock is Internally Adapted for T1

or E1 Usage in the Host Mode.

CꢀReceive Signal Level Indication from -2.5dB to

-36dB in T1 Mode and -2.5dB to -44dB in E1

Mode in Approximate 2.5dB Increments
