Low power architecture -- Class AB, current

drive, output stage through a centre tapped

transformer to facilitate power supply switching

between 5.0V and a lower voltage. (3.3V in the

reference design) This gives a reduction in

power consumption.

480mW power consumption with a typical G.lite

signal.

600mA current driving capability

Positive +5.0V and one lower supply. (3.3V in

the reference design)

Switching power supplies to save power

Thermal overload shutdown

Four programmable receive gains

Opamp for a low pass filter in the receive path

Undedicated opamp with separate power down

control (used as a transmit path filter in the

reference design)

Separate power down control for Tx and Rx

path

48-pin TQFP (7x7x1.4mm) package

TQFP48 (7x7x1.40)

ORDERING NUMBER: STLC1512

1.0 GENERAL DESCRIPTION

The STLC1512 G.lite line driver chip contains the line

driver as well as part of the receive path required in a

central office G.lite modem. It provides an interface

between the AFE chip (STLC1511) and the tele-

phone line. The line driver chip has been designed

with low power consumption, high signal to noise

plus distortion ratio and high current driving capabili-

ty.
