ADSL Drivers/Receivers for Customer Premise
Equipment
MAX4363
The MAX4361/MAX4362/MAX4363 are a family of high-
performance ADSL drivers and drivers/receivers ideal
for the upstream transmit path and the downstream
receive path of customer premise equipment. These
devices operate from a single 5V supply and deliver up
to 12.5dBm average line power for DMT modulated sig-
nals, meeting the requirements of full-rate ADSL. SFDR
at full output power is typically -75dBc at 100kHz.
The MAX4361 is a differential line driver with a fixed
gain of 3.1V/V. The gain is set by three internal resistors.

The MAX4362 is a dual amplifier with shutdown intend-
ed for use as a differential IN/differential OUT driver
with gain set with external resistors
The MAX4363 is a quad amplifier with shutdown intended
for use as a differential IN/differential OUT driver/receiver
combination with gain set with external resistors.
The MAX4362/MAX4363 feature a low-power shutdown
mode. When the SHDN pin is pulled high, the supply
current drops to 70µA, and the amplifier’s outputs are
placed in a high-impedance disable mode. Connect
SHDN to GND for normal operation.
