DS26324  
3.3V, 16-Channel, E1/T1/J1  
Short-Haul Line Interface Unit

GENERAL DESCRIPTION  
FEATURES  
16 E1, T1, or J1 Short-Haul Line Interface  
Units  
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  
support E1/T1/J1 that requires no external  
termination. 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  
TE-CSBGA, the smallest package available for a  
16-channel LIU.  
Independent E1, T1 or J1 Selections  
Fully Internal Impedance Match Requires No  
External Resistors  
Software-Selectable Transmit and Receive-  
Side Impedance Match  
Crystal-Less Jitter Attenuator  
Selectable Single-Rail and Dual-Rail Mode  
and AMI or HDB3/B8ZS Line Encoding and

Digital/Analog Loss of Signal Detection as  
per T1.231, G.775 and ETS 300 233  
APPLICATIONS  
T1 Digital Cross-Connects  
ATM and Frame Relay Equipment  
Wireless Base Stations  
External 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
