The recommended power-up sequence is to apply the analog power supply (AVDD) first, followed by the digital power supply (DVDD) and then the clock signal. This ensures proper initialization of the device.
To optimize performance in a noisy environment, ensure proper PCB layout, use decoupling capacitors, and consider adding a ferrite bead or common-mode choke to filter out high-frequency noise. Additionally, use a low-jitter clock source and consider using a clock jitter cleaner.
The LMH1981MT can support clock frequencies up to 1.5 GHz. However, the maximum clock frequency may vary depending on the specific application and PCB layout. It's recommended to consult the datasheet and perform thorough testing to ensure reliable operation.
The LMH1981MT is a highly configurable device. To configure it for a specific video format, refer to the datasheet and programming guide. You'll need to set the appropriate registers to select the desired video standard, resolution, and other parameters.
The typical power consumption of the LMH1981MT varies depending on the specific application and operating conditions. However, according to the datasheet, the typical power consumption is around 1.2W. It's recommended to consult the datasheet and perform thorough testing to determine the actual power consumption in your specific application.
