Notes:
DD
1. All timing is referenced to the 50% level of the waveform. Input test levels are V
2. The minimum SCLK cycle time is based on a single Si3220 connected to the SPI bus. If multiple Si3220s are

connected to the same SPI bus, please contact a Silicon Laboratories representative for the recommended minimum
SCLK cycle time for your application.
