Note 1: Data in “Typ” column is at 3.3V, 25°C unless otherwise stated. Parameters are for design guidance only
and are not tested.
2: 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%
