NOTE: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when the
device is mounted in a test socket with maintained transverse airflow greater than 500 lfpm. The device will meet specifications after
thermal equilibrium has been reached under these conditions.
All parameters measured at ƒ  fMAX using a crystal input unless noted otherwise.
Terminated at 50 to VDDO/2.
NOTE 1: XTAL_IN can be overdriven by a single-ended LVCMOS signal. Please refer to Application Information section.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at VDDO/2.
NOTE 3: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 4: These parameters are guaranteed by characterization. Not tested in production.
