73K222AL-IH

The 73K222AL-IH is one member of the 73K222AL family which is designed as the highly integrated single-chip modem IC that includes the DPSK and FSK modulator / demodulator functions, so this device can be used in call progress and handshake tone monitor and a tone generator capable of tone required for European applications. Also it integrates analog, digital, and switched-capacitor array functions on a single substrate.

Features of the 73K222AL-IH are:(1)One-chip CCITT V.22, V.21, Bell 212A and Bell 103 standard compatible modem data pump; (2)Full-duplex operation at 0-300 bit/s (FSK) or 600 and 1200 bit/s (DPSK); (3)Pin and software compatible with other TDK Semiconductor Corporation K-Series 1-chip modems; (4)Interfaces directly with standard microprocessors (8048, 80C51 typical); (5)Serial or parallel microprocessor bus for control; (6)Serial port for data transfer; (7)Both synchronous and asynchronous modes of operation including V.22 extended overspeed; (8)Call progress, carrier, precise answer tone (2100 or 2225 Hz), and long loop detectors; (9)DTMF, and 550 or 1800 Hz guard tone generators; (10)Test modes available: ALB, DL, RDL, Mark, Space, Alternating bit patterns; (11)The precise automatic gain control of the 73K222AL-IH allows 45 dB dynamic range; (12)CMOS technology for low power consumption using 60 mW @ 5V; (13)Single +5 volt supply; (14)PLCC and PDIP packages.
