FEMTOCLOCK CRYSTAL-TO-HCSL CLOCK GENERATOR
Table 6B. HCSL AC Characteristics, VDD = VDDOA = VDDOB = 3.3V±5%, TA = -40°C to 85°C
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: All measurements are taken at 125MHz and 156.25MHz.
NOTE 1: Please refer to the Phase Noise Plot.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions.
Measured at the differential cross points.
NOTE 3: This parameter is defined in accordance with JEDEC Standard 65.
