High Sampling Rate DSP Evaluation Board

I'm currently using an EVAL-ADAU1761 as a frequency mixer to generate references for a lock-in amplifier. I take the signals from two photodiodes (f1 = 11kHz and f2 = 27kHz) and generate f1 + f2 = 38kHz and f2 - f1 = 16kHz using Sigma Studio. If I were to make f1 and f2 higher in frequency, say 40 kHz each, f1 + f2 = 80 kHz would exceed the 48 kHz limit for this board given that the sampling rate is set to the maximum 96 kHz. What other options are there available for evaluation boards with higher sampling rates?
