For our application we need to communicate with a lot of individual AD9910 cores. Keeping the circuitry as simple as possible we want to switch the CS-Line via an adress-decoder and feed the remaining serial communications signal to all connected ICs in parallel. While this is certainly possible for "controller => AD9910" communication on SDIO & SCLK, the datasheet remains unclear, whether this can be done with the SDO-pin as well.
When configured as a serial output line, does the SDO-pin go into a high-impedance state when the IC does not communicate and therefore release control of a common SDO-bus-line to other cores?
Thanks in advance
