2.3.4 CX20441 LD Description
The CX20441 Line Driver (LD) supports full-rate (T1.413 and G.992.1) and G.lite (G.992.2) ADSL modems. It is optimized for
ideal ADSL performance providing low noise, high bandwidth, and superior linearity. The CX20441 LD transmits a DMT
modulated signal in the 25 – 132 kHz band.
The CX20441 LD operates from a +5V supply. Internal load balancing prevents the CX20441 LD from loading the system
when in a power down state. A block diagram of the CX20441 LD is shown in Figure 2-4.
