DS26334: 16-port short / long-haul Line Interface Interface Unit

In Electronic Infomation Category: D | on April 20,2011

DS26334 16-port short / long-haul Line Interface Interface Unit (LIU), support 3.3V power supply E1/T1/J1 system. Just a list of materials to support E1/T1/J1, no external termination. Using non-invasive monitoring, the best high-impedance mode and ADUM1100AR datasheet and 1:1 or 1 +1 redundant operation Enhanced backup support. Built-in frequency synthesizer master clock input from all the way to produce different frequencies E1/T1/J1 clock. The chip also provides two reference clock outputs, TE-CSBGA 256-pin package, is the smallest 16-channel LIU product package.

Key features

16-channel E1, T1 or J1 short / long-haul line interface unit

can be independently selected E1, T1 or J1 mode

impedance matching is provided internally, no external resistor

can be software selected to send, receive side of the impedance matching circuit

Crystal-less jitter attenuator

Optional power supply and ADUM1100AR price and dual supply operation, and ADUM1100AR suppliers and AMI or HDB3/B8ZS line codec

AIS detection, generator

digital / analog signal loss detection, in line with T1.231, G.775, and ETSI 300 233 standard

T1/J1 E1 mode or an external master clock can be a 2.048MHz or 1.544MHz multiplier (the clock by internal adaptive adjustment for T1 or E1 mode)

received signal level indicator in the T1 mode is-2.5dB to-38dB, E1 mode is-3dB to-43dB, in increments of 2.5dB

two built-in BERT detector for diagnostics

support Intel, Motorola mode 8-bit parallel port and 4-wire serial

to send short-range protection

G.772 non-intrusive monitoring

receiver can monitor the cable attenuation of 12dB to 30dB to 30dB adjusted 14dB resistive attenuator

T1/E1 line with the latest standards-ANSI T1.102, AT & T Pub * 11, T1.231, T1.403, ITU- T G.703, G.742, G.775, G.823, ETS 300 166 and ETS 300 233

3.3V single power supply with 5V I / O tolerance

meet the JTAG IEEE 1149.1 Boundary Scan

Application

ATM and Frame Relay equipment

E1/T1/J1 LAN / WAN Router

E1/T1/J1 multiplexer and channel backup

ISDN interface to a group

T1 digital cross-connect

Wireless Base Station
