MN195007 Hardware Specifications
Panasonic Communications Co., Ltd..
1. Overview
1.1 Overview
The MN195007 is a 16-bit fixed-point DSP that implements high-speed signal processing. A
DSP core, program memory, and work memory assembled on-chip can be combined with an
analog front end (AFE) device to build a modem. The MN195007 is integrated 1 chip Digital
Signal Processing LSI for FAX modem, Data modem and Voice control and it is suitable as a
built-in modem solution.
The V.34 FAX and Voice modem LSI MN195006 is the similar pin layout with the MN195007,
so the MN195006 can be replaceable to the MN195007 with minor design change.
