SXT6282  
Octal E1 Digital Interface with CRC-4 Monitoring and Jitter/Wander  
Suppression  
General Description  
Features  
SXT6282 is an eight-channel E1 digital interface. It inte-  
grates an E1 dejitter phase locked loop, an E1 retiming  
function and a CRC-4 monitor function for each E1 trans-  
mitter and a CRC-4 monitoring function for each E1  
receiver. It is optimized for SDH applications and can used  
in conjunction with the SXT6251 (21 E1 mapper).  
• Octal E1 transceiver digital interface  
• Performs the jitter attenuation function on a gapped  
clock supplied by a PDH or SDH multiplexer  
• Performs CRC4 performance monitoring on both  
transmit and receive sides  
• Provides a retiming function on the transmit side for  
SDH applications (demapped E1 tributaries)  
Applications  
• Built-in HDB3 encoder/decoder  
• Compatible with SXT6251 for STM-0/1 applications  
• SDH 21 or 63 E1 multiplexer  
• STM-0 and STM1 SDH add/drop multiplexer  
• PDH NxE1 multiplexer  
• DCS  
• Compatible with LXT334 and the Next Generation  
octal LIU  
• Microprocessor programmable  
• Low power, 3.3 Volt operation, 5 V tolerant i/o  
• IEEE 1149.1 (JTAG) compliant  
• Microwave radio  
• LQFP - 144 surface mount packaging  
• Satellite  
• Compatible with ITU G.703, G.704, G.706, G.707,  
G.775 (Draft 1996), G.783 and G.742  
• Test equipment  
• Protection Switch  
•Industrial temperature operating range -40°C to +85°C.
