transmit path converts digital data-to-analog signals and performs a
smoothing operation before presenting the signals to the line driver.
Line Driver
The integrated CX20441 line driver is more cost effective and
power sensitive than a discrete solution, and is optimized for
full-rate and G.lite ADSL modems. It has high bandwidth,
low noise and superior linearity.
