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 V

NOTE: XTAL parameters (initial accuracy, temperature stability, aging and total stability) are guaranteed by manufacturing.
NOTE 1: This parameter is defined in accordance with JEDEC standard 65.
NOTE 2: Please refer to the phase noise plots.
NOTE 3: Please see the FemtoClock NG Ceramic 5x7 Modules Programming guide for more information on PLL feedback modes and the
optimum configuration for phase noise.
NOTE 4: 12kHz to 20MHz.

.
NOTE 2: Nominal oscillator gain: Pull range divided by the control voltage tuning range of 3.3V. E.g. for ADC_GAIN [6:0] = 000001 the pull
range is ± 12.5ppm, resulting in an oscillator gain of 25ppm ÷ 3.3V = 7.57ppm/V.
NOTE 3: For best phase noise performance, use the lowest K
