The Leader in Host Signal Processing (HSP) Modem Technology
PCT2303N for AMR & MDC
Motherboard integration of the modem subsystem has been problematic to date, in large part due to FCC and
other international telecom certification processes that delay the introduction of a motherboard when the
modem鈥檚 analog I/O (codec and DAA) circuitry was physically soldered to the board. Resolving homologation/
certification issues for OEMs is one of the key objectives of the AMR/MDC specification.
With an open, Industry-standard riser solution, a system manufacturer is free to implement audio and/or modem
functions on the motherboard at a lower bill of materials (BOM) cost than would be possible by deploying these
functions in either industry-standard expansion slots or in a proprietary method.
PC-TEL has streamlined the traditional modem into the Host Signal Processing (HSP) solution. Operating with
the Pentium class processors, HSP becomes part of the host computer鈥檚 system software. It requires less power
to operate and less physical space than standard modem solutions. PC-TEL鈥檚 HSP modem is an easily
integrated, cost-effective communications solution that is flexible enough to carry you into the future.
The PCT2303N chip set is an integrated direct access arrangement (DAA) and CODEC that provides a
programmable line interface to meet requirements. ThePCT 2303N chip set is available in two 16-pin small
outline packages (AC鈥?7 interface on PCT303A and phone-line interface on PCT303L). The chip set eliminates
the need for an AFE, an isolation transformer, relays, opto-isolators, and 2- to 4-wire hybrid. The PCT2303N chip
set dramatically reduces the number of discrete components and cost required to achieve compliance with
regulatory requirements. The PCT303A complies with AC鈥?7 Interface specification Rev. 2.1.
