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
bases or communication clocks use this formula::
Peripheral Clock Jitter = -----------------------------^D-----^C----^L---^K------------------------------
⎛
⎝
P^----e^---r^--i^--p^---h^---e^--r^---a^---lF^---B^-O---i^-St^--C--R^---a^---t^--e^----C^----l^--o^---c^--k^{- ⎠⎞}
For example: Fosc = 32 MHz, DCLK = 3%, SPI bit rate clock, (i.e., SCK) is 2 MHz.
SPI SCK Jitter =
---------^D----^C----^L---^K---------
