4 Input and Output Connections

The BUF634ADRBEVM and BUF634ADDAEVM are equipped with SMA connectors to easily connect to the benchtop signal generators and analysis equipment. Additionally, the EVM also includes RCA input jacks and a 3.5-mm output jack that can be used with the two BUF634A devices in a differential audio buffer configuration. The connections to the SMA outputs include 50–Ω termination resistors to easily connect to 50–Ω impedance test equipment. The inputs are high impedance, but can be easily terminated to 50 Ω as well by populating resistors R1 and R4. Route the outputs to the test equipment using cables with a 50–Ω characteristic impedance, and connect the inputs to the signal source with as short of cables as possible for best results in the default configuration.
