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
