The recommended power-up sequence is to apply power to the analog power pins (AVDD and DVDD) first, followed by the digital power pins (DVDD and PVDD). This ensures that the analog circuitry is powered up before the digital circuitry.
The TVP5146M2PFPR can be configured for a specific video format using the I2C interface. The device has a set of registers that control the video format, including the video standard, resolution, and pixel clock frequency. Consult the datasheet for the specific register settings for each video format.
The TVP5146M2PFPR supports clock frequencies up to 148.5 MHz, which is sufficient for most video formats, including 1080p60 and 4K30.
The TVP5146M2PFPR has a thermal pad on the bottom of the package that must be connected to a heat sink or a thermal plane on the PCB to dissipate heat. Ensure that the thermal pad is properly connected and that the PCB is designed to dissipate heat effectively.
The recommended layout and routing for the TVP5146M2PFPR involves keeping the analog and digital signals separate, using differential pairs for the video signals, and minimizing the length of the clock signal traces. Consult the datasheet and application notes for more detailed guidelines.
