GENERAL DESCRIPTION
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.
and a 28-lead TSSOP_EP with an exposed lead frame (ePAD).
Operating from ±12 V supplies, th
e AD8016 requires only 1.5 W
for details) while driving 20.4 dBm of power downstream using
(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 th
e AD8016 to be used as the central office
(CO) terminal driver in ADSL, HDSL2, VDSL, and proprietary
xDSL systems.
