The min/max specifications are guaranteed over this range. 2 Guaranteed by characterization. 3 TTL input values are 0 V to 3 V, with rise/fall times ≤3 ns, measured between the 10% and 90% points. 4 Timing figures obtained using default drive strength value (0xD5) in register subaddress 0xF4. ANALOG SPECIFICATIONS At AVDD = 3.15 V to 3.45 V, DVDD = 1.65 V to 2.0 V, DVDDIO = 3.0 V to 3.6 V, PVDD = 1.71 V to 1.89 V. Operating temperature range, unless otherwise noted. Recommended analog input video signal range: 0.5 V to 1.6 V, typically 1 V p-p. Table 4.
