[TDK]
DESCRIPTION
The 73K324L is a highly integrated single-chip modem IC which provides the functions needed to design a Quad-mode CCITT and Bell 212A compatible modem capable of operation over dial-up lines. The 73K324L adds V.23 capability to the CCITT modes of TDK Semiconductor Corporations 73K224 one-chip modem, allowing a one-chip implementation in designs intended for European markets which require this added Modulation mode. The 73K324L offers excellent performance and a high level of functional integration in a single IC. The device supports V.22bis, V.22, Bell 212A, V.21, and V.23 operating modes, allowing both synchronous and asynchronous operation as defined by the appropriate standard.
The 73K324L is designed to appear to the Systems Engineer as a microprocessor peripheral, and will easily interface with popular one-chip microcontrollers (80C51 typical) for control of modem functions through its 8-bit multiplexed address/data bus. A serial control bus is available for applications not requiring a parallel interface. An optional package with only the serial control bus is also available. Data communications occurs through a separate serial port.
FEATURES
· One chip Multi-mode CCITT V.22bis, V.22, V.21, V.23 and Bell 212A compatible modem data pump
· FSK (75, 300, 1200 bit/s), DPSK (600, 1200 bit/s), or QAM (2400 bit/s) encoding
· Pin and software compatible with other TDK Semiconductor Corporation K-Series family one-chip modems
· Interfaces directly with standard microprocessors (8048, 80C51 typical)
· Serial and parallel microprocessor bus for control
· Selectable asynch/synch with internal buffer/debuffer and scrambler/descrambler functions
· All synchronous (internal, external, slave) and Asynchronous Operating modes
· Adaptive equalization for optimum performance over all lines
· Programmable transmit attenuation (16 dB, 1 dB steps), and selectable receive boost (+18 dB)
· Call progress, carrier, answer tone, unscrambled mark, S1, and signal quality monitors
· DTMF, answer, calling, SCT and guard tone generators
· Test modes available: ALB, DL, RDL; Mark, Space and Alternating bit pattern generators
· CMOS technology for low power consumption (100 MW @ 5 V) with power-down mode (15 mW @ 5V)
· 4-wire full duplex operation in all modes
