hi,
in my project i am using isl12057 RTC for a date and time,the VT-200-F crystal provide 32.768KHz frequency. my circuit have stray capacitance of 7.5+pf, and parallel capacitance for crystal is 5 pf, Now in this circuit condition i got an increment delay of 3 sec after every 24 hours. we can't change the board design also
pleases guide me how can i fix this problem and delay reduces to zero. and also reduce the stray capacitance of the board.
