1 VDE = differential error voltage. VCME = common-mode error voltage. V = maximum deviation between outputs.
Full-scale output voltage = VFS = 2 × (VREFHI – VREFLO). See the Accuracy section on page 14.
2 Measured on two outputs differentially as CLK and DB(0:11) are driven and STSQ and XFR are held LOW.
3 Measured on two outputs differentially as the other four are transitioning by 5 V. Measured for both states of INV.
4 Measured from 50% of falling CLK edge to 50% of output change. Measurement is made for both states of INV.
5 Operation at 85°C ambient temperature requires a thermally optimized PCB layout (see Applications section), minimum airflow of 200 lfm, input clock rate not
exceeding 120 MHz, black-to-white transition ≤ 4 V, and CL ≤ 200 pF.
