Quad Adaptive Differential Pcm Processor - National Semiconductor

The TP11362A is a quad (4) channel Adaptive Differential Pulse Code Modulation (ADPCM) transcoder, fully compat- ible to ITU G.726 recommendation in 40 kbps, 32 kbps, 24 kbps, 16 kbps and ANSI 32 kbps modes. The TP11362A ADPCM processor CAN operate on up to 8 independent channels in an 8 kHz frame. Each channel is individually configured, supporting both full and half duplex operation. All input/output transfers occur on an interrupt basis using se- rial, double buffered data Registers Together with Nationals TP3054 57 COMBO or TP3070 71 COMBO II devices, the TP11362A forms complete ADPCM channels with Codec/ filtering.
