1.0 System Overview
1.1 Functional Summary
The RS8973 High-bit-rate Digital Subscriber Line (HDSL) transceiver is an
integral component of Conexant's HDSL chipset. System performance of the
chipset allows 2-pair T1, 1-pair E1, 2-pair E1, and 3-pair E1 transmission. With
its built-in frequency synthesizer, it can easily be configured through software for
variable rate Symmetric DSL over Single Pair (SDSL) applications, using a single
10.24 MHz crystal/clock as reference. It can operate at data rates between
144 kbps and 2320 kbps. The major building blocks of a typical HDSL T1/E1
terminal are shown in
