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: s SK70725A - Enhanced Digital Signal Processor (EDSP) s SK70721- I...
