ADC DC CHARACTERISTICS
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).
TxDAC IOUTFS = 20 mA, differential output with 1:1 transformer with source and load termination of 50 Ω, F
IOUN full-scale current = 80 mA, f
Use external amplifier to drive additional load.
Internal VCO operates at 200 MHz , set to divide-by-1.
Because CLKOUT2 is a divided down version of OSCIN, its jitter is typically equal to OSCIN.
CLKOUT2 is an inverted replica of OSCIN, if set to divide-by-1.
