CRYSTAL-TO-LVDS/LVCMOS FREQUENCY SYNTHESIZER
AC Electrical Characteristics
Table 6. AC Characteristics, VDD = VDDOB = VDDOC = VDDO_REF = TA = -40°C to +85°C
NOTE: QBx, QC LVCMOS outputs are characterized up to 125MHz.
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 within a bank of outputs at the same supply voltage and with equal load conditions.
NOTE 2: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 3: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at VDDOB/2.
