Description
TP5088 DTMF Generator for Binary Data October 1991 TP5088 DTMF Generator for Binary Data General .
Features
* Y Y Y Y Y Y Y Y Y Y Direct microprocessor interface Binary data inputs with latches Generates 16 standard tone pairs On-chip 3 579545 MHz crystal-controlled oscillator Better than 0 64% frequency accuracy High group pre-emphasis Low harmonic distortion MUTE output interfaces to speech network Low pApplications
* 4-bit binary data is decoded directly without the need for conversion to simulated keyboard inputs required by standard DTMF generators With the TONE ENABLE input low the oscillator is inhibited and the device is in a low power idle mode On the low-to-high transition of TONE ENABLE data is latched iTP5088 Distributors
