1 Temperature range TMIN to TMAX is −40°C to +85°C. The minimum/maximum specifications are guaranteed over this range.
2 Guaranteed by characterization.
3 Nominal sync depth is 300 mV at 100% sync depth range.
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 is 0.5 V to 1.6 V, typically 1 V p-p.
