SC14428E1MW1VD - Brand New Panduit IC Chips
-
Description
The SC14428E1MW1VD is a 3.0 Volt CMOS IC optimized for handling audio, signal, and data processing within a DECT basestation. It integrates an ADPCM transcoder, a low power CODEC, and Analog Frontend. With direct connections to analog or ISDN line interfaces, the SC14428E1MW1VD is designed to be compatible with various radio interfaces. It also features a dedicated TDMA controller for physical layer slot formats and radio control. The integrated National Semiconductor's standard CR16A processor core handles the higher protocol stack, while programmable I/O ports can be configured for various purposes such as chip selects for I/O expanders, Serial Flash memory, interrupt sources, or I/O. The digital serial interface can be configured for compatibility with codecs and ISDN devices using different data formats including m-Law, a-Law, linear, or transparent.
