I'm a DFAE in Japan. The customer is thinking of adopting ADF4154 or ADF4156, but he wants to use the input frequency at 78MHz.In this case, is it possible to operate at the low frequency if the slew rate is kept at 400V / µs?
My customer is asking if ADI can make the firmware available for the Cypress PSOC (CY7C68013) microcontroller that does the conversion from USB to serial that is on the ADF4154 PC interface board (parat number EVAL-SDP-CS1Z)?
I have a current prototype design with a ADF4154, the ability to achieve quick settling (<20us) using the fast-lock feature is critical, for production I would like to add a lock detect indication and so am considering a replacement part.
All our Frequency Synthesizers parts can have the Reference (REFIN) signal removed, and unlock will result. Reconnecting REFIN will result in the part locking to the correct frequency. ADF41xx parts will behave in this manner. Our Frequency Synthesizers…
