To begin the design process, determine the following:
- Input voltage range
- Use the supply voltage of the device that is driving the TXV0106-Q1 device to determine the input voltage range. For a valid logic-high, the value must exceed the positive-going input-threshold voltage (Vt+) of the input port. For a valid logic low the value must be less than the negative-going input-threshold voltage (Vt-) of the input port.
- Output voltage range
- Use the supply voltage of the device that the TXV0106-Q1 device is driving to determine the output voltage range.
- RGMII Compliant
- For the TXV0106-Q1 to meet RGMII timing specifications, parameters like frequency, CLOAD and input rise or fall transition have to be met. Make sure each channel does not exceed a maximum frequency of 125 MHz, use a CLOAD no greater than 5 pF, and use an input rise or fall translation no greater than 2 ns/V.
