1 See the Explanation of Test Levels section.
2 Gain error and gain temperature coefficients are based on the ADC only (with a fixed 1.23 V external reference and a 1 V p-p differential analog input).
3 TxDAC IOUTP_FS = 20 mA, differential output with 1:1 transformer with source and load termination of 50 Ω, fOUT = 5 MHz, 4x interpolation.
4 IOUTN full-scale current = 80 mA, fOSCIN = 80 MHz, fDAC =160 MHz, 2x interpolation.
5 Use external amplifier to drive additional load.
6 Internal VCO operates at 200 MHz; set to divide-by-1.
7 Because CLKOUT2 is a divided-down version of OSCIN, its jitter is typically equal to OSCIN.
8 CLKOUT2 is an inverted replica of OSCIN, if set to divide-by-1.
