    Rashmi,

    Make certain that you have at least a 1 uF cap from Vin to GND and that Vin and Vc arre connected. You need a resistor to Rd as well as the ones you have added. connect a 0.1 ceramic from Vref to GND.

    Apply a 15 volt supply between Vin and GND. Verify that Vref comes up and when that happens the clock should start.

    Regards,

    John
