SK70720 and SK70721 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: s SK70720 MDSL Digital Signal Processor (MDSP) s SK70721 Integrated Analog Fr...
