General Description
The MAX9480/MAX9481/MAX9482 low-power, low-dis-
tortion, class-G, high-current asymmetric digital sub-
scriber line (ADSL) drivers offer Rail-to-Rail
output and
are ideal for ADSL in central-office applications.
Operating from ±5V and ±2.5V supplies, the drivers
incorporate two high-speed current-feedback preampli-
fiers driving two fixed-gain class-G buffers. The buffers
can deliver 20.4dBm average line power with a signal
crest factor of 5.3, and are designed to be directly DC or
AC bridged across a 1:2.5 transformer.
The MAX9480/MAX9481/MAX9482 employ an active line
termination scheme for incoming signals that eliminates
the need for back-match resistors, reducing line-card
power consumption at full rate to less than half of that
required by conventional class-AB line-driver circuits.
The MAX9480 includes a hybrid network and two low-
noise, fixed-gain-of-4.6V/V receive amplifiers. The part is
designed to recover the receive signal to the same level
as that of a conventional line interface circuit that incor-
porates a 1:2 transformer and standard back-matched
hybrid, without degrading signal-to-noise ratio (SNR) or
line-impedance sensitivity. The MAX9481 provides only
the preamplifiers and buffers without the hybrid or
receivers. The MAX9482 provides preamplifiers, buffers,
and uncommitted receive amplifiers. All devices have a
low-output-impedance shutdown function for saving
power when not transmitting.
At full-rate 20.4dBm discrete multitone data transmission
(DMT), the total dynamic power dissipation is only
680mW (MAX9480/MAX9482) or 655mW (MAX9481).
The MAX9480/MAX9481 are available in a 20-pin TSSOP
package and the MAX9482 is available in 28-pin TSSOP
and 32-pin QFN packages. All devices operate over the
extended -40°C to +85°C temperature range.
