General Description
PCT1789W General Description
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's 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 mostcompact, 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.
