PERFORMANCE CHARACTERISTICS
Unless otherwise stated, all performance characteristics
are for:
? Power Supply, V CC = 3.3 V
? Ambient Temperature, T A = 25 o C
? Video Input 1.0 V p-p , 10-step grayscale.
? RF inputs/outputs into 75 ? load.
NOTE:
Specifications only valid for envelope demodulation.
Table 6. High Frequency Characteristics
The parameters listed are based on the type of test condi-
tions found in the column Type.
? A = 100% tested
? B = 100% Correlation tested
? C = Characterized on samples
? D = Design parameter
See the “Characterization Measurement Conditions” on
page 8 for each C type parameter.
