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 telephone line. The line driver chip has been designed with low power consumption, high signal to noise plus distortion ratio and high current driving capability.

■ 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
