Nominal Differential Full Scale = .766 V * 2 = 1.53 Vp-p differential for S5 = 0; Nominal Differential Full Scale = .766 Vp-p differential for S5 = 1 (see Fig. X)

2 IAVDD and IDrVDD are measured with an analog input of 10.3MHz, -0.5dBFs, sine wave, rated Encode rate and in LVDS output mode. See Typical Performance

Characteristics and Applications section for IDrVDD. 3 Power Consumption is measured with a DC input at rated Encode rate in LVDS output mode
