NOTES: 1. Maximum ratings are those values beyond which damage to the device may occur. For

functional operation, voltages should be restricted to the Recommended Operating Conditions.

2. ESD data available upon request.

ELECTRICAL CHARACTERISTICS (Parameter Type: A–100% Tested, B–100% Correlation Tested, C–Characterized on

Samples. D–Design Parameter, VCC = 5.0 V, TA = 25C, Video input 1.0 Vpp, 10 step greyscale. Step 3 [typ. 80%] modulation depth for

PAL; Step 5 [typ 90%] modulation for SECAM L; P/S ration Step 3 [typ 14.5 dB]. RF output into 75 Ω load. Unless otherwise noted.)

(Specifications only valid for envelope demodulation.)
