SC14425
Description
The SC14425SC14425 is a 3.3 Volt CMOS IC optimized to handle all the audio, signal and data processing needed within a DECT base station. An ADPCM transcoder, a very low power 14 bit Codec and Analog Frontend are integrated. Direct connections towards analog or ISDN line interface. The SC14425 has an on-chip dedicated flexible DSP optimized for tele applications caller-id, handsfree and allows easy connection to digital telephone answering machine devices. The SC14425 is designed to be patible with many radio interfaces. A dedicated TDMA controller handles all physical layer slot formats and radio control. The integrated National Semiconductor’s standard CR16B processor core takes care of all the higher protocol stack. Programmable I/O ports can be configured as chip selects for I/O expanders, Serial Flashes, interrupt source or I/O. A digital serial interface can be configured to interface to industry-standard c odecs and ISDN devices with µ-Law, a-Law, linear or...
