Texas Instruments recommends a 4-layer PCB with a solid ground plane and a separate power plane for the VCC and VCCA pins. Additionally, it's recommended to use a 50-ohm transmission line for the differential signals and to keep the signal traces as short as possible.
To ensure signal integrity, it's recommended to use a controlled impedance PCB, keep the signal traces as short as possible, and use a common mode filter or a common mode choke to reduce electromagnetic interference (EMI). Additionally, it's recommended to use a signal termination resistor to match the impedance of the transmission line.
The maximum operating temperature range for the SN74VMEH22501AGQLR is -40°C to 125°C. However, it's recommended to operate the device within the recommended operating temperature range of -40°C to 85°C for optimal performance and reliability.
It's recommended to power up the VCCA pin before the VCC pin, and to power down the VCC pin before the VCCA pin. This ensures that the internal voltage regulators are properly powered up and down to prevent damage to the device.
Texas Instruments recommends using a 10-uF ceramic capacitor and a 1-uF ceramic capacitor in parallel, placed as close as possible to the VCC and VCCA pins. This helps to filter out noise and ensure stable power supply to the device.
