All parameters measured at IJ fMAX using a crystal input unless noted otherwise.
Terminated at 50Ω to VDDO/2.
NOTE 1: XTAL_IN can be overdriven relative to a signal a crystal would provide.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at VDDO/2.
NOTE 3: These parameters are guaranteed by characterization. Not tested in production.
NOTE 4: This parameter is defined in accordance with JEDEC Standard 65.
