GENERAL DESCRIPTION
The AD5011 is an analog front end for two pair or single
pair HDSL applications that use 1168 kbps or 2.32 Mbps
data rates. The device integrates all the transmit and receive
functional blocks. A standard serial interface is used to
communicate with the DAC and ADC. The filters in both
the transmit and receive paths are programmable which
allows adaptive HDSL to be performed also. The part is
available in a 48-pin LQFP package and is specified for a
temperature range of -40 oC to +85 oC.
