73K302L  
Bell 212A, 103, 202  
Single-Chip Modem  
April 2000  
DESCRIPTION  
FEATURES  
The 73K302L is a highly integrated single-chip  
modem IC which provides the functions needed to  
construct a Bell 202, 212A and 103 compatible  
modem. The 73K302L is an enhancement of the  
73K212L single-chip modem with Bell 202 mode  
features added. The 73K302L is capable of 1200 or  
0-300 bit/s full-duplex operation over dial-up lines.  
4-wire full-duplex capability and a low speed back  
channel are also provided in Bell 202 mode. The  
73K302L recognizes and generates a 900 Hz soft  
carrier turn-off tone, and allows 103 for 300 bit/s  
FSK operation. The 73K302L integrates analog,  
digital, and switched-capacitor array functions on a  
single substrate, offering excellent performance and  
a high level of functional integration in a single  
28-pin DIP or PLCC package. The 73K302L  
operates from a single +5V supply with very low  
power consumption.  
One-chip Bell 212A, 103 and 202S/T standard  
compatible modem data pump  
Full-duplex operation at 0-300 bit/s (FSK), 1200 bit/s  
(DPSK) or 0-1200 bit/s (FSK) forward channel with or  
without 0-150 bit/s back channel  
Full-duplex 4-wire operation in Bell 202 mode

Interfaces directly with standard microprocessors  
(8048, 80C51 typical)  
Serial port for data transfer  
Both synchronous and asynchronous modes of  
operation  
Call progress, carrier, precise answer tone  
(2225 Hz), soft carrier turn-off (SCT), and FSK mark  
detectors  
DTMF, answer, and SCT tone generators  
The 73K302L includes the DPSK and FSK  
modulator/demodulator functions, call progress and  
handshake tone monitors, test modes, and a tone  
generator capable of producing DTMF, answer, and  
900 Hz soft carrier turn-off tone. This device  
supports Bell 202, 212A and 103 modes of  
Test modes available: ALB, DL, RDL, Mark, Space,  
Alternating bit patterns  
CMOS technology for low power consumption using  
60 mW @ 5V from a single power supply
