I have just started using ADuC848BSZ32-5 ( Ver: C21) batch Code: #1113; 2091821.1
My problem is few devices are giving good clock output and few are giving clock output with jitter and some are not oscillating at all. Tried changing the crystal, no luck. I am using 32.768 KHz Crystal. Can you please let me know what should be the load capacitance of the crystal ( 6 pf or 12 pF ) ?
Do I need to connect a capacitor from pin 32 (XTAL1) or 33 (XTAL2) to Ground ? if yes, what should be its value ?
Kindly help me resolve this issue
