TP11368
Octal Adaptive Differential PCM Processor
General DescriptionThe TP11368isan octal(8) channel Adaptive Differential
Pulse Code Modulation (ADPCM) transcoder, fully compat-
ibleto ITU G.726 recommendationin40 kbps,32 kbps, kbps,16 kbps and ANSI32 kbps modes.The TP11368
ADPCM processorcan operateonupto16 independent
channelsinan8 kHz frame. Each channelis individually
configured, supporting bothfullandhalf duplex operation.All
input/output transfers occuronan interrupt basis usingse-
rial, double buffered data registers. Togetherwith National’s
TP3054/57 COMBO®or TP3070/71 COMBOII devices,the
TP11368 forms complete ADPCM channels with Codec/
filtering.
Features CCITT G.726 compatibleat40,32,24,16 kbps ANSI T1.301 compatibleat32 kbps 16-channel half-duplex (encodeor decode)or 8-channel
full-duplex operationin8kHz frame Each channel individually configurable Selectable μ-lawor A-law PCM coding Asynchronous16 MHz master clock operation TTLand CMOS compatible inputsand outputs 28-pin PLCCor 24-pinDIP packages Power consumptionoftyp.6 mWat +5Vper full-duplex
