The MC03AX1456 ADSL Line Driver provides a single chip analog
front end to interface the ADSL Transceiver to the line transformer.
The MC03AX1456CO is designed to fulfill the central office
requirements. The MC03AX1456RT is optimized for use at the remote
terminal (i.e. consumer premises). The ADSL Line Driver provides three
differential ports: a transmit and a receive port to interface to the ADSL
Transceiver’s transmit and receive ports, respectively; and a bidirectional
line port.
The transmit port incorporates a high–pass filter and a programmable
gain stage with three settings. The receive port incorporates a
programmable HF boost and a programmable gain stage, each with three
settings, as well as a high pass–filter.
Hybrid balance for echo cancellation
Defined termination impedance to the line
Programmable transmit gain (3 settings)
Programmable receive gain (3 setting)
Programmable HF boost (3 setting)
Transmit band for CO is 26KHz–1104KHz
Transmit band for the RT is 26KHz–138KHz
Frequency ripple <0.5dB (CO and RT)
Standby mode for lower power dissipation (CO and RT)
