GENERAL DESCRIPTION
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.726 compatible at 40, 32, 24, 16 kbps n ANSI T1.301 compatible at 32 kbps n 16-channel half-duplex (encode or decode) or 8-channel full-duplex operation in 8 kHz frame n Each channel individually configurable n Selectable µ-law or A-law PCM coding n Asynchronous 16 MHz master clock operation n TTL and CMOS compatible inputs and outputs n 28-pin PLCC or 24-pin DIP packages n Power consumption of typ. 6 mW at +5V per full-duplex channel n On-Chip Power-On-Reset n −40˚C to +85˚C operating temperature range n Single 5V supply Block Diagram DS012902-1 FIGURE 1.
