1 The SNR of a 14-bit ADC was measured with an ENCODE rate of 105 MSPS and an AIN of 170 MHz. The resultant SNR was known to be limited by the jitter of the clock,
not by the noise on the AIN signal. From this SNR value, the jitter affecting the measurement can be back calculated.
2 Driving the REFIN input buffer. The crystal oscillator section of this input stage performs up to only 30 MHz.
3 The charge pump output compliance range is functionally 0.2 V to (CP_VDD 0.2 V). The value listed here is the compliance range for 5% matching.
4 The input impedance of the CLK1 input is 1500 . However, to provide matching on the clock line, an external 50 load is used.
5 Measured as peak-to-peak between DAC outputs.
6 For a 4.02 k resistor from DRV_RSET to GND.
7 Assumes a 1 mA load.
