The device integrates all the transmit and receive functional blocks. A standard serial interface is used to municate 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 o C to +85 o C.
