NOTE(S):
Recommended Operating Conditions,
NTSC CCIR 601 operation, and CLK frequency = 27 MHz. As the above
parameters are guaranteed over the full temperature range, temperature coefficients are not specified or required. Typical values
are based on nominal temperature, i.e., room temperature, and nominal voltage, i.e., 5 V or 3.3 V.
