12 Video Characteristics
Each of the characteristics listed in Table 21 is classified as one of the following types:
• A—100% tested
• B—100% correlation tested
• C—Characterized on samples
• D—Design parameter
See Section 14, “Characterization Measurement Conditions,” for each C-type parameter.
Unless otherwise stated, V_CC = 5.0V, ambient temperature = 25°C, and video input is 1 Vp-p, with 10-step
grey scale and RF output into 75-Ω load.
NOTE
Specifications are only valid for envelope demodulation.
