LXT351  
T1/E1 Short Haul Transceiver with Crystal-less Jitter Attenuation  
Datasheet  
The LXT351 is a full-featured, fully-integrated transceiver for T1 and E1 short-haul  
applications. The LXT351 is software switchable between T1 and E1 operation, and offers pulse  
equalization settings for all short-haul T1 and E1 line interface (LIU) applications.  
The LXT351 offers an Intel/Motorola compatible parallel port for microprocessor control. The  
device incorporates advanced crystal-less digital jitter attenuation in either the transmit or  
receive data path starting at 3 Hz. B8ZS/HDB3 encoding/decoding and unipolar or bipolar data  
I/O are selectable. Loss of signal monitoring and a variety of diagnostic loopback modes can  
also be selected.  
Applications  
■ SONET/SDH tributary interfaces  
■ Digital cross connects  
■ Public/private switching trunk line  
interfaces  
■ Microwave transmission systems  
Product Features  
■ Fully integrated transceivers for Short-Haul ■ Transmit/receive performance monitors  
T1 or E1 interfaces  
■ Crystal-less digital jitter attenuation  
—Select either transmit or receive path  
with Driver Fail Monitor Open (DFM) and  
Loss of Signal (LOS) outputs  
■ Selectable unipolar or bipolar data I/O and  
B8ZS/HDB3 encoding/decoding  
—No crystal or high speed external clock  
required  
■ QRSS generator/detector for testing or  
monitoring  
■ Meet or exceed specifications in ANSI  
T1.403 and T1.408; ITU I.431, G.703,  
G.736, G.775 and G.823; ETSI 300-166  
and 300-233; and AT&T Pub 62411  
■ Supports 75 Ω (E1 coax), 100 Ω (T1  
twisted-pair) and 120 Ω (E1 twisted-pair)  
applications  
■ Output short circuit current limit protection  
■ Local, remote and analog loopback  
capability  
■ Compatible with Intel’s LXT360/361 T1/  
E1 long haul/short haul transceiver  
(Universal LIU)  
■ Multiple register parallel interface  
compatible with both Intel and Motorola  
microprocessors  
■ Fully restores the received signal after  
transmission through a cable with  
attenuation of 18dB, at 1024 kHz  
■ Available in 28-pin PLCC and 44-pin  
■ Five pulse equalization settings for T1  
PQFP packages  
short-haul applications
