32 kHz crystal oscillator  
The CYW89820 includes a 32 kHz oscillator to provide accurate timing during low power operations. Figure 2  
shows the 32 kHz XTAL oscillator with external components and Table 3 lists the oscillator’s characteristics. This  
oscillator can be operated with a 32 kHz or 32.768 kHz crystal oscillator or be driven with a clock input at similar  
frequency. The XTAL must have an accuracy of ±250 ppm or better per the BT spec over temperature and  
including aging. The default component values are: R1 = 10 Mand C1 = C2 = ~6 pF. The values of C1 and C2 are  
used to fine-tune the oscillator.
