IC card interface

TDA8002

Notes

1. It may be necessary to put capacitors from XTAL1 and XTAL2 to ground depending on the choice of crystal or

resonator.

2. When the oscillator is stopped in mode 1, XTAL1 is set to HIGH.

3. The transition time and duty cycle definitions are shown in Fig.13;

5. CLKOUT transition time and duty cycle do not need to be tested.
