SC14402VJG

The SC14402VJG is designed as a 3.0V CMOS chip optimized to handle all the audio, signal and data processing needed within a DECT handset. An ADPCM transcoder, a very low power CODEC and analog frontend is integrated. Direct connections towards microphone and a dynamical loudspeaker are provided.

SC14402VJG has nineteen features. (1)Integrated DECT baseband transceiver optimized for GAP handsets according to ETS 300 175-2, 175-3 & 175-8. (2)2.95V to 3.6V operating voltage. (3)Very low power in active and paging mode. (4)Max 5V battery input. (5)Embedded 16 bit compactRISC micro controller (CR16A) with programmable clock speeds. (6)4 kbyte on-chip data memory. (7)ACCESSBUS or MICROWIRE interfaces can be handled. (8)One full duplex ADPCM transcoder. (9)On-chip 14-bit linear CODEC. (10)8 upto 38dB gain differential microphone input buffer. (11)100ohms loudspeaker driver. (12)Software controlled gain on audio input and output. (13)Peak hold ADC for RSSI measurement. (14)Three general purpose inputs can be multiplexed on an 8bit ADC with selectable ranges. (15)Advanced battery management unit. (16)On board dedicated TDMA instruction co-processor (DIP). (17)Eight programmable control signals for radio front end. (18)Serial interface to control radio front end circuitry. (19)Full support of all data formats.

Some pin description of SC14402VJG are concluded as follow. (1)Its pin 1 is SCLK which is the output (slope controlled). (2)Its pin 2 is Vdd which is digital supply voltage. (3)Its pin 3 is Vss which is digital ground. (4)Its pin 4 to pin 11 is PD7..0 which is tri-state output. (5)Its pin 12 is RFCLK which is output (clope controlled), 10MHz clock output. And so on.

SC14402VJG is designed such that SC14402VJG is compatible with many radio interfaces. A dedicated TDMA controller handles all physical layer slot formats and radio control. National semiconductors standard compactRISC CR16A 16 bit microcontroller with external ROM takes care of all the higher protocol stack. And so on. At present we have got so much information about this IC and we would try hard to get more information about it.
