FEMTOCLOCK CRYSTAL-TO-LVCMOS/LVTTL CLOCK GENERATOR
AC Electrical Characteristics
Table 6A. AC Characteristics, VDD = VDDO = 3.3V ± 5%, TA = -40°C to 85°
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: Refer to Phase Noise Plot.
Table 6B. AC Characteristics, VDD = VDDO = 2.5V ± 5%, TA = -40°C to 85°
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: Refer to Phase Noise Plot.
Table 6C. AC Characteristics, VDD = 3.3V ± 5%, VDDO = 2.5V ± 5%, TA = -40°C to 85°
NOTE: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when the device is
