DESCRIPTION
The 73K224BL is a highly integrated single-chip modem IC which provides the functions needed to construct a V.22bis compatible modem, capable of 2400 bit/s full-duplex operation over dial-up lines. The 73K224BL is an enhancement of the 73K224L single chip modem, which adds the hybrid hook switch control, and driver to the 73K224L. The 73K224BL integrates analog, digital, and switched-capacitor array functions on a single chip, offering excellent performance and a high level of functional integration in a 32-Lead PLCC package.
The 73K224BL operates from a single +5 V supply for low power consumption.
The 73K224BL is designed to appear to the systems designer as a microprocessor peripheral, and will easily interface with popular single-chip micro processors (80C51 typical) for control of modem functions through its 8-bit multiplexed address/data bus or via an optional serial control bus. An ALE control simplifies address demultiplexing. Data communications normally occur through a separate serial port.
The 73K224BL is pin and software compatible with the 73K222BL, allowing system upgrades with a single component change.
FEATURES
• Includes features of 73K224L single-chip modem
• On chip 2-wire/4-wire hybrid driver and off hook relay buffer driver
• One-chip multi-mode V.22bis/V.22/V.21 and Bell 212A/103 compatible modem data pump
• FSK (300 bit/s), DPSK (600, 1200 bit/s), or QAM (2400 bit/s) encoding
• Software compatible with other TERIDIAN Semiconductor K-Series one-chip modems
• Interfaces directly with standard micro processors (80C51 typical)
• Parallel or serial bus for control
• Selectable internal buffer/debuffer and scrambler/descrambler functions
• All asynchronous and synchronous operating modes (internal, external, slave)
• Adaptive equalization for optimum perform ance over all lines
• Programmable transmit attenuation (16 dB, 1 dB steps), selectable receive boost (+18 dB)
• Call progress, carrier, answer tone, unscrambled mark, S1, and signal quality monitors
• DTMF, answer and guard tone generators
• Test modes available: ALB, DL, RDL, mark, space, alternating bit, S1 pattern generation and detection
• CMOS technology for low power consumption (typically 100 mW @ 5 V) with power-down mode (15 mW @ 5 V)
• TTL and CMOS compatible inputs and outputs
