LVCMOS CLOCK GENERATOR
Table 5. AC Electrical Characteristics, VDD = AVDD = 3.3V ± 0.3V, 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 1: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at VDD/2.
NOTE 2: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 3: Measured between coincident rising output edges of Q0:Q4 and Q/2.
NOTE 4: Defined as the time difference between the input reference clock and the average feedback input signal when the PLL is locked and
the input reference frequency is stable.
NOTE 5: These parameters are guaranteed by characterization. Not tested in production.
