TP11368 Octal Adaptive Differential PCM Processor March 1997 TP11368 Octal Adaptive Differential PCM Processor General Description The TP11368 is an octal (8) channel Adaptive Differential Pulse Code Modulation (ADPCM) transcoder, fully compatible to ITU G.726 recommendation in 40 kbps, 32 kbps, 24 kbps, 16 kbps and ANSI 32 kbps modes. The TP11368 ADPCM processor can operate on up to 16 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 serial, double buffered data registers. Together with National’s TP3054/57 COMBO ® or TP3070/71 COMBO II devices, the TP11368 forms complete ADPCM channels with Codec/ filtering. Features n CCITT G.
