GENERAL DESCRIPTION
The
high output current dual amplifier is designed for
the line drive interface in Digital Subscriber Line systems such
as ADSL, HDSL2, and proprietary xDSL systems. The drivers
are capable, in full-bias operation, of providing 24.4 dBm
output power into low resistance loads, enough to power a
20.4 dBm line, including hybrid insertion loss.
The
is available in a low cost 24-lead SOIC_W_BAT
and a 28-lead TSSOP_EP with an exposed lead frame (ePAD).
Operating from ±12 V supplies, the
requires only 1.5 W
of total power dissipation (refer to the Power Dissipation section
for details) while driving 20.4 dBm of power downstream using
the xDSL hybrid in Figure 35 and Figure 36. Two digital bits
(PWDN0, PWDN1) allow the driver to be capable of full
performance, an output keep-alive state, or two intermediate
bias states. The keep-alive state biases the output transistors
enough to provide a low impedance at the amplifier outputs
for back termination.
The low power dissipation, high output current, high output
voltage swing, flexible power-down, and robust thermal
packaging enable the
to be used as the central office
(CO) terminal driver in ADSL, HDSL2, VDSL, and proprietary
xDSL systems.
