SK70725A/SK70721  
Enhanced Multi-Rate DSL Data Pump Chip Set  
Datasheet  
The Enhanced Multi-Rate DSL Data Pump (EMDP) is a variable-rate transceiver that provides  
symmetric full-duplex communication on one twisted wire pair using a 2B1Q line code with  
echo-cancellation. The EMDP operates in either framed or Transparent modes and supports  
channelized, cell and packet applications. Symmetrical line rates may be at any speed between  
272 and 1,168 kbps. Performance is specified at 272, 400, 528 784 and 1,168 kbps for payloads  
of 4, 6, 8, 12 or 18 channels at 64 kbps and 16 kbps of overhead. The EMDP chip set consists of  
two devices:  
SK70725A - Enhanced Digital Signal Processor (EDSP)  
SK70721- Integrated Analog Front-End (IAFE)  
The IAFE is a fully integrated CMOS analog front-end which includes D/A converter, filters,  
and transmit line drivers. Receiver functions include analog echo canceller, AGC, A/D converter  
modulator and VCXO functions. The EDSP incorporates all digital signal processing required  
for A/D conversion, echo-cancellation, data scrambling and adaptive equalization as well as  
transceiver activation state machine control  
Applications  
High speed symmetrical Internet access  
Wireless base station access  
Extended range fractional T1/E1 transport WAN access for 10BaseT and ATM LANs  
Digital pairgain systems from 4 to 18  
Video Conferencing Systems
