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 circuits are powered up before the digital circuits.
The TVP5147M1PFP can be configured for different video input formats using the I2C interface. The device has a set of registers that control the video input format, such as the input standard, clock frequency, and data format. Refer to the datasheet for the specific register settings for each format.
The TVP5147M1PFP supports clock frequencies up to 74.25 MHz for SD and HD video formats, and up to 148.5 MHz for 3G-SDI video formats.
The TVP5147M1PFP has a thermal shutdown feature that shuts down the device when the junction temperature exceeds 150°C. To handle this feature, ensure that the device is properly heat-sinked, and implement a thermal monitoring system to detect when the device is approaching the thermal shutdown threshold.
The recommended layout and routing for the TVP5147M1PFP involves keeping the analog and digital signals separate, using differential pairs for clock and data signals, and minimizing the length of the traces to reduce signal degradation. Refer to the datasheet for specific layout and routing guidelines.
