PCT1789W
The HSP56 World MicroModem PCT1789W chip set provides a
highly integrated modem solution consisting of the PCT789T-C, PCT303D
and PCT303W. PCTEL has integrated over half of the discrete DAA into a
silicon DAA PCT303D and PCT303W two-chip solution. The PCT1789W
chip set provides a programmable, multi-country compliant PCI modem
solution. This high level of integration of the HSP56 World MicroModem
chip set and the reduction in circuit board size makes the HSP56 World
MicroModem the most compact, power saving ( 55mW total solution
@3.3V ), and cost-effective solution for 56Kbps internal modems available
for the desktop, notebook and sub-notebook market.

PCT1789W
The PCT1789W provides a PCI bus interface, CODEC/DAA interface, input/output port, interrupt control, and
power management function. This device was designed to work efficiently with PC-TEL’s advanced Host
Signal Processing (HSP) Modem software to perform V.90 data/fax/voice functions. The figure below shows
the 1789W-hardware block diagram using the PCT789T-C, coupled with the PCT303D and PCT303W. This
solution is compliant with ACPI D3 Cold Wake on Ring function.
The HSP Modem reference design, evaluation units, user’s manual, schematics and Gerber files will be
provided on request to qualified customers.
