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: Characterized with outputs at the same frequency using the loop filter components for the 35Hz loop bandwidth.
Refer to Jitter Attenuator Loop Bandwidth Selection Table.
NOTE 1: Refer to the Phase Noise Plot.
NOTE 2: PSNR results achieved by injecting noise on VCCA supply pin with no external filter network.
NOTE 3: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 4: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at the output differential
cross points.
NOTE 5: Lock Time measured from power-up to stable output frequency.
