TP11368
Octal Adaptive Differential PCM Processor
General Description
The TP11368 is an octal (8) 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 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 se-
rial, 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.
