AVH316D

APLUS AVxx16 Series GENERAL DESCRIPTION: The AVH316B, AVH316C, AVH316D, AV0716C, AV0716D, AV1416D, AV2116A, AV2816A is a single-chip synthesizing CMOS VLSI that can synthesize voice up to 3.5,7,14,21,28 seconds using APLUS qualified coding algorithm (LOGPCM). Customer speech data will be edited and programmed into ROM by changing one mask during one mask during the device fabrication. FEATURES: 1. Single power supply can operate from 2.4v through 5v. 2. The total voice duration is about 3.5,7,14,21,28,42 seconds could be partitioned up to 16 voice sections. Each voice section could have 4 playing lengths; the longest one is the origional voice+mute length. 3. Voice + mute length could up to 22 seconds ( 11 seconds in AVH316 ) (6k sampling rate) for each voice section. 4. One 112 voice-steps table, could be partitioned up to 16 subtables of steps. 5. 5 mask option of playback speed : 1> 4.3K ; 2> 5.0K ; 3> 6.0K ; 4> 7.5K ; 5> 10.0K ( Hz ) 6. 1 trigger input (TG): with resistive schmitt input (270K---1M) for CDS interface. sequential function : once the input was triggered sequentially the device will response by one subtable of voice_step sequentially and cyclically , from subtable_m ( m= 1 -16 ) to user defined subtable_n ( n= 1 - 16 ) . random function : Once the input was trigger , the device will response from subtable_m ( m: 1 - 16 ) to subtable_n ( n: 1 - 16 ) at random . snooze function : use 2 subtables : 1st stores ringing voice , playing when time's up. 2nd...
