Description
32 MHz crystal load capacitor
32 MHz crystal load capacitor
Load capacitance for analogue power
supply voltage regulators
Load capacitance for digital power supply
voltage regulators
DC block to antenna and match
Note: For RF connector a LP filter can be
connected between this C, the antenna
and good ground in order to remove
conducted spurious emission by using
1.8pF in parallel with 1.6nH
32.768 kHz crystal load capacitor (if low-
frequency crystal is needed in application)
Discrete balun and match

Precision resistor for current reference
generator to RF part
32 MHz Crystal
Optional 32.768 kHz watch crystal (if low-
frequency crystal is needed in application)
