A good PCB layout for the LMH0034MA involves keeping the input and output traces short and away from each other, using a solid ground plane, and placing decoupling capacitors close to the device. A 4-layer PCB with a dedicated power plane and a dedicated ground plane is recommended.
To ensure proper termination for HD-SDI applications, use a 75-ohm termination resistor at the output of the LMH0034MA, and make sure the output is AC-coupled to the load. Additionally, use a 75-ohm transmission line to connect the output to the load.
The maximum cable length supported by the LMH0034MA depends on the specific application and the type of cable used. However, as a general guideline, the device can support cable lengths of up to 100 meters for HD-SDI applications.
To configure the LMH0034MA for 3G-SDI applications, set the SDI_MODE pin to a logic high, and use an external 1.62V voltage regulator to power the device. Additionally, use a 3G-SDI-compliant input signal and ensure the output is AC-coupled to the load.
The power consumption of the LMH0034MA depends on the specific application and the operating frequency. However, the typical power consumption is around 350mW at 2.97Gbps, and 450mW at 3Gbps.
