These parameters are characterized, but not tested in manufacturing.
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:
For example, if SYSCLK = 80 MHz and SPI bit rate = 20 MHz, the effective jitter is as follows:
Frequency calibrated at 25°C and 3.3V. The TUN bits can be used to compensate for temperature drift.
This information is preliminary.
