IL9200AN

IL9200AN, IL9200AD Microcircuit IL9200AN, IL9200AD (FUNCTIONAL EQUIVALENT OF HT9200A HOLTEK) is generator DTMF of signals. The IC is purposed for formation standard DTMF the signals used for frequency coding of dialed number. It is used in telecom systems, consumer electronic devices. Performed function – generation of standard DTMF signals and component frequencies. It is recommended to use ILA9170, ILA9270 for decoding of DTMF signals generated by IC IL9200A. The microcircuit is available in 8-pin DIPcase MS-001BA and SO-case MS-012AA. 08 01 N-suffix DIP-case Features: Supply voltage Ucc from 2,0 to 5,5 V; Serial mode of data input; Clock frequency 3,58 MHz; Low standby current consumption; Internal timer for writing; Low total harmonic distortion ; Operating temperature from -20 to 75 oC 08 01 D - suffix SO-package Fig. 1 – View of microcircuits IL9200AN- DIP package (MS-001BA) & IL9200AD -SO-package (MS-012AA) CE 01 08 Ucc X2 02 07 DTMF X1 03 06 DATA GND 04 05 CLK Fig. 2 – Pin assignment diagram Ver.00/13.04.2009 1 IL9200AN, IL9200AD Table1 - Pin Description Pin Number 01 02 03 04 05 06 07 08 Pin Name (Symbol) CE Х2 Х1 GND CLK DATA DTMF Ucc Description Chip select (active low) Oscillator output Oscillator input Common pin Clock input for serial mode Data input for serial mode Output of the DTMF signal Voltage supply pin X1 X2 DATA CLK 3,58 MHz Crystal/Resonator Oscillator Serial Data Input Circuit DTMF Generator Control Circuit C...
