STLC1511  
NorthenLite™ G.lite BiCMOS  
Analog Front-End Circuit  
PRODUCT PREVIEW  
Wide transmit (~80dB) and receive (~69dB)  
dynamic range to limit the external filtering  
requirements for extended loop reach operation  
Programmable tx gain: 0 ÷ -32dB in 2dB steps  
14-bit D/A converter in transmit path  
Programmable rx gain: 0 ÷40dB in 0.5dB steps  
12-bit A/D converter in receive path  
TQFP64  
ORDERING NUMBER: STLC1511  
Integrated phase-locked loop with an externall  
LC or crystal oscillator  
The STLC1511 transmit path consists of a 14-bit  
Nyquist rate D/A converter, followed by a program-  
mable gain amplifier (TxPGA). The transmit gain is  
programmable from 0 to -32dB in 2dB steps.  
Low power: 300mW @ 5.0V  
64-pin TQFP package  
1.0 GENERAL DESCRIPTION  
The STLC1511 receive path contains a buffer ampli-  
fier followed by a programmable gain amplifier (RxP-  
GA), a low pass anti-aliasing filter, and a 12-bit  
Nyquist rate A/D converter. The RxPGA is digitally  
programmable from 0 to 40dB in 0.5dB steps.  
The STLC1511 G.lite Analog Front End (AFE) chip  
implements the analog transceiver functions required  
in both a central office modem and a customer  
premise modem. It connects the digital modem chip  
with the loop driver and hybrid balance circuits. The  
STLC1511 has been designed with excellent dynam-  
ic range in order to greatly reduce the external filter-  
ing requirements at the front end. The AFE chip and  
its companion digital chip along with a loop driver, im-  
plement the complete G.992.2 DMT modem solution.
