STLC1512  
NorthenLite™ G.lite Loop Driver  
PRODUCT PREVIEW  
■
■
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.  
TQFP48 (7x7x1.40)  
ORDERING NUMBER: STLC1512  
■
■
600mA current driving capability  
Positive +5.0V and one lower supply. (3.3V in  
the reference design)

1.0 GENERAL DESCRIPTION  
Four programmable receive gains  
Opamp for a low pass filter in the receive path  
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.  
Undedicated opamp with separate power down  
control (used as a transmit path filter in the  
reference design)
