2:

Data in “Typ” column is at 3.3V, 25°C unless otherwise stated.

These parameters are characterized by similarity but are not tested in manufacturing. This specification is

based on clock cycle by clock cycle measurements. To calculate the effective jitter for individual time base

or communication clocks used by peripherals use the formula:

Peripheral Clock Jitter = DCLK / √(FOSC/Peripheral bit rate clock)

Example Only: Fosc = 80 MHz, DCLK = 3%, SPI bit rate clock, (i.e. SCK), is 5 MHz

SPI SCK Jitter = [ DCLK / √(80 MHz/5 MHz)] = [3%/ √16] = [3% / 4] = 0.75%
