DATA SHEET

DESCRIPTION (continued)

The 73K324BL is pin and software compatible with

the 73K222BL and 73K224BL, allowing system

upgrades and product differentiation with a single

component change.

The 73K324BL is designed to be a complete V.22bis

compatible modem on a chip. The complete modem

requires only the addition of the phone line interface,

a control microprocessor, and RS-232 level

converter for a typical system. Many functions were

included to simplify implementation of typical modem

designs. In addition to the basic 2400 bps QAM,

600/1200 bps DPSK and 300/1200 bps FSK

modulator/demodulator sections, the device also

includes

synch/asynch

converters,

scrambler/descrambler, call progress tone detect,

DTMF tone generator capabilities and handshake

pattern detectors. Test features such as analog loop,

digital loop, and remote digital loopback are

supported. Internal pattern generators are also

included for self-testing.

FEATURES (continued)

• Adaptive equalization for

performance over all lines

optimum

• 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, SCT, and guard tone

generators

• Test modes available: ALB, DL, RDL, mark,

space, alternating bit, S1 pattern

• 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
