HT9200A/HT9200B
Functional Description
The HT9200A/B are DTMF generators for MCU interfaces. They are controlled by a MCU in the serial mode or the parallel mode (for the HT9200B only). Serial Mode (HT9200A/B) The HT9200A/B employ a data input, a 5-bit code, and a synchronous clock to transmit a DTMF signal. Every digit of a phone number to be transmitted is selected by a series of inputs which consist of 5-bit data. Of the 5 bits, the D0(LSB) is the first received bit. The HT9200A/B will latch data on the falling edge of the clock (CLK pin). The relationship between the digital codes and the tone output frequency is shown in Table 1. As for the control timing diagram, refer to Figure 1. When the system is operating in the serial mode a pull-high resistor is attached to D0~D3 (for parallel mode) on the input terminal.

HT9200A/HT9200B
For the HT9200B, the S/P pin has to be connected low for serial mode operation. Parallel Mode (HT9200B) The HT9200B provides four data inputs D0~D3 to generate their corresponding DTMF signals. The S/P has to be connected high to select the parallel operation mode. Then the input data codes should be determined. Finally, the CE is connected low to transmit the DTMF signal from the DTMF pin. The TDE time (about 6ms) will be delayed from the CE falling edge to the DTMF signal output. The relationship between the digital codes and the tone output frequency is illustrated in Table 2. As for the control timing diagram, see Figure 2. When the system is operating in the parallel mode, D0~D3 are all in the floating state. Thus, these data input pins should not float.
