Note 1: These parameters are characterized, but not tested in manufacturing.

2: This jitter specification is based on clock-cycle by clock-cycle measurements. To get the effective jitter for

individual time-bases on communication clocks, use the following formula:

EffectiveJitter = -------------------------D----C----L---K--------------------------

------------------S----Y---S----C----L----K--------------------

CommunicationClock

For example, if SYSCLK = 40 MHz and SPI bit rate = 20 MHz, the effective jitter is as follows:

EffectiveJitter = D-----C----L--K-- = D-----C----L--K--
