Design Notes
Ensure proper decoupling of the AVDD and DVDD pins with 0.1 uF ceramic capacitors placed as close to the pins as possible. Additionally, use a 10 uF bulk capacitor on the main supply rail. The ADV7391 operates from 1.71 V to 3.63 V, so verify that the supply voltage is within this range under all load conditions. Refer to the datasheet's power supply recommendations for optimal performance.
For the LFCSP package, ensure the exposed pad (EP) is soldered to a ground plane for thermal and electrical performance. Use multiple vias to connect the EP to the ground plane. Keep analog and digital ground planes separate and connect them at a single point to minimize noise. Follow the layout guidelines in the datasheet to reduce crosstalk between digital and analog signals.
The ADV7391 is NRND (not recommended for new designs). For new projects, consider using the ADV7393BCPZ or other alternatives. Also, ensure that the digital input timing (PCLK, HSYNC, VSYNC) meets the datasheet specifications to avoid video glitches. Incorrect I2C configuration can lead to improper output; initialize the device according to the datasheet's register map.
