Other Parts Discussed in Thread: CDCLVP1204
How should the CDCLVP1204 EVM be modified to operate with VCC = 2.5V? The data sheet for the buffer indicates that VAC_REF should not be used when VCC < 3.0V. The eval board input circuit is set up to AC couple the input clock and uses the VAC_REF output to bias the input. In our case, we would still AC couple the input, but its not clear how to modify the bias circuit for VCC = 2.5V
