Multi-Rate DSL Data Pump Chip Set

Datasheet

The Multi-Rate DSL Data Pump is a complete, variable-rate transceiver that provides full duplex

communication on two wires using echo-canceller-with-hybrid and 2B1Q line coding

technology. It provides symmetrical line rates from 272 to 784 kbps. Performance specifications

are defined at the 272, 400, 528, and 784 kbps data rates which provide a payload of 4, 6, 8, or

12 64 kbps channels with a 16 kbps overhead channel. The MDSL Data Pump also supports

applications where the payload is unchannellized.

The MDSL Data Pump chip set consists of two devices:

■ SK70720 MDSL Digital Signal Processor (MDSP)

■ SK70721 Integrated Analog Front-End (IAFE)

The IAFE is a fully integrated CMOS analog front-end IC which includes transmitter line

drivers, filters, and 2B1Q encoding functions along with the receiver hybrid, AGC, A-to-D

converter modulator and VCXO functions. The MDSP 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 residential Internet access

■ Extended Range fractional T1/E1 transport ■ WAN access for LAN routers

■ 4 to 12-channel digital pair-gain ■ Video Conferencing

■ Wireless base station to switch access
