SK70704/SK70706
784 Kbps HDSL Data Pump Chip Set
Datasheet
The HDSL Data Pump is a chip set consisting of the following two devices: s SK70704 Analog Core Chip (ACC) s SK70706 HDSL Digital Transceiver (HDX)
The HDSL Data Pump is a 2-wire transceiver which provides echo-cancelling and 2B1Q line coding. It incorporates transmit pulse shaping, filtering, line drivers, receive equalization, timing and data recovery to provide 784 kbps, clear-channel, “data pipe” transmission. The Data Pump provides Near-End Cross-Talk (NEXT) performance in excess of that required over all ANSI and ETSI test loops. Typical transmission range on 26 AWG (0.4 mm) cable exceeds 13 kft (4 km) in a noise-free environment or 9.5 kft (2.9 km) with ANSI-specified noise levels.
