ESCRIPTION

The PCT789T-A device provides the interface and

buffering between PCI bus and CODEC serial interface,

input/output port, interrupt control, and auto power-down

management. This device works with CODEC, DAA,

and PC-TEL鈥檚 advanced host signal processing

software to perform data/fax/voice functions. The figure

below shows the hardware block diagram of an internal

modem using the PCT789T-A device.

PCT789T-A is a single-chip modem controller which

supports PC-TEL Host Signal Processing 56Kbps

modem solution. The PCT789T-A provides the most

compact, power-saving, and cost-effective solution for

56Kbps internal modems. It can also be used with other

hardware such as audio chip and video-conferencing

chip sets for combo board applications.

鈥?Low power consumption (35 mW operating @ 3.3 V)

and auto power management

鈥?Supports Win 95, Win 98, Win NT 4.0 and NT 5.0

operating systems

鈥?Support for D3 cold, VAUX, Wake-on-Ring

鈥?Minimum system configuration:

Pentium MMX 166 MHz +, AMD K6 MMX 200 MHz +,

or Cyrix 6x86MX PR200 +; 256K Cache; 16 MB RAM

鈥?HSP speakerphone via software upgrade with full-

duplex sound chip

鈥?V.80 for Point to Point H.324 video conferencing
