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: Device operation is guaranteed for the standard audio reference frequencies of 11.2896MHz, 12.288MHz, 16.384MHz,
16.9344MHz, 18.432MHz, 22.5792MHz and 24.576MHz. A variation of up to ±1000ppm in reference clock is acceptable at these
frequencies.
NOTE 2: Measured at 22.5792MHz and 24.576MHz input clock.
NOTE 3: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 4: Measured at 24.576MHz input clock and cycle N = 512.
NOTE 5: Measured at 24.576MHz input clock from 100Hz to 5MHz.
