Product Summary
The SC14424BVJG is a Complete Baseband Processor for DECT Base Stations. An ADPCM transcoder, a very low power CODEC and Analog Frontend are integrated. Direct connections towards analog or ISDN line interface. The SC14424BVJG is designed to be compatible with many radio interfaces. A dedicated TDMA controller handles all physical layer slot formats and radio control.
