adc0808 clock
you can provide the clock from controller itself.. for external clock try using two 7474 in series as has been given here.. chck this : http://www.engineersgarage.com/microcontroller/8051projects/interface-AD...

Two 'D'Flip flop is required

Two 'D'Flip flop is required for give clock to ADC0808. In MC crystal oscillator output is given to clk of D flip flop, and then 'D' flip flop output is given to ADC.
