AC Electrical Characteristics
Table 5. AC Characteristics, VCC = 3.3V±5%, VCCO_LVCMOS = VCCO_LVPECL = 3.3V±5% or 2.5V±5%, VEE = 0V,
TA = -40°C to 85°C
See Parameter Measurement Information section.
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.
NOTE 1: Defined as skew between outputs at the same supply voltage, same frequency, and with equal load conditions.
Measured at the output differential cross points.
NOTE 2: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 3: Please refer to the Phase Noise plots.
