DESCRIPTION
The 73K222AL is a highly integrated single-chip modem IC which provides the functions needed to construct a CCITT V.22, V.21 and Bell 212A compatible modem, capable of 1200 bit/s full-duplex operation over dial-up lines. The 73K222AL is an enhancement of the 73K212L/AL single-chip modem which adds V.22 and V.21 modes to the Bell 212A and 103 operation of the 73K212AL. In Bell 212A mode, the 73K222AL provides the normal Bell 212A and 103 functions and employs a 2225 Hz answer tone. The 73K222AL in V.22 mode produces either 550 or 1800 Hz guard tone, recognizes and generates a 2100 Hz answer tone, and allows 600 bit/s V.22 or 0-300 bit/s V.21 operation.
FEATURES
• One-chip CCITT V.22, V.21, Bell 212A and Bell 103 standard compatible modem data pump
• Full-duplex operation at 0-300 bit/s (FSK) or 600 and 1200 bit/s (DPSK)
• Pin and software compatible with other TERIDIAN Semiconductor Corporation K-Series 1-chip modems
• Interfaces directly with standard microprocessors (8048, 80C51 typical)
• Serial or parallel microprocessor bus for control
• Serial port for data transfer
• Both synchronous and asynchronous modes of operation including V.22 extended overspeed
• Call progress, carrier, precise answer tone (2100 or 2225 Hz), and long loop detectors
• DTMF, and 550 or 1800 Hz guard tone generators
• Test modes available: ALB, DL, RDL, Mark, Space, Alternating bit patterns
• Precise automatic gain control allows 45 dB dynamic range
• CMOS technology for low power consumption using 60 mW @ 5V
• Single +5 volt supply
• PLCC package
