Frequently Asked Questions
What voltage range should I use for the positive supply (Vdd)?
The required Vdd typically is 5 V, with an acceptable operational range between 4.5 V and 5.5 V.
How do I connect the composite video input signal (CVBS)?
Connect it via Pin 25; a positive-going 1 V peak-to-peak input is required, utilizing a 100 nF capacitor connection.
Which method should be used to achieve a non-interlaced display?
Use the ODD/EVEN output (Pin 41) which provides a 25 Hz signal synchronized with the CVBS input's field sync pulses.
What are the warnings regarding operating limits on this device?
Operating at or above limiting voltage values may cause permanent damage, and these stress ratings do not imply normal operation conditions.
