8 / 65 page ADS62P19 SLAS937 – APRIL 2013 www.ti.com TIMING REQUIREMENTS: LVDS AND CMOS MODES (1) (continued) Typical values are at TA = +25°C, AVDD = 3.3 V, DRVDD = 1.8 V, sampling frequency = 250 MSPS, sine-wave input clock, 1.5-VPP clock amplitude, CLOAD = 5 pF (2), and R LOAD = 100 Ω (3), unless otherwise noted. Minimum and maximum values are across the full temperature range of TMIN = –40°C to TMAX = +85°C, AVDD = 3.3 V, and DRVDD = 1.7 V to 1.9 V.

(8) Data valid refers to a logic high of 1.26 V and a logic low of 0.54 V. (9) The output buffer enable is controlled by serial interface register 40h. The output buffer becomes active when serial control data for the output buffer are latched on the 16th SCLK falling edge when SEN is low. Table 2.
