QWe cannot find the Siward part shown in the ADF7021-VDBXZ Evalboard design
(TXO812025LJ-19.68MHz-3.0R). Can you recommend another part?
AI do not have another recommendation. However any other TCXO manufacturer (like
Fox, Valpey Fisher etc.) should be fine once the TCXO meets the frequency
tolerance, temperature specs etc. of the application. Also the TCXO should have
an 0.8Vpk-pk output.
