LMX2594: When multiple LMX2594 are used together with LMK04828B, can SPI interfaces be tied together?

Hello,

My clock tree uses one LMK04828 (clkin_sel0 as SDO OD mode) and three LMX2594 (muxout as SDO). Can I connect the SCK, SDI and SDO of these four devices together, and then select the chip through cs_n?

1. I asked this question because I noticed the description that The MUXout pin will always be low for the address portion of the transaction in datasheet of LMX2594. I don't know whether this description refers to whether lmx2594 can keep MUXOUT output low at this time, or whether other circuits on the board need to force the signal to be low?
2. CLKIN_sel0 of lmk04828 is used as SDO, it can be explicitly configured as OD mode (clkin_sel0_mux = SPI readback, clkin_sel0_type = output OD). However, when lmx2594 MUXOUT is used as SDO, the datasheet does not specify its output format, nor does it find the relevant configuration register. According to the general understanding, OD / OC outputs can be directly connected together. If it is a push-pull structure, it is not OK. Therefore, it is unclear how to deal with the SDO of SPI interface when multiple 2594 are used together.
3. According to previous development experience, SPI interfaces SDOs of different devices are all connected together, and there are often inexplicable problems. I don't know whether TI has verified the application of the above connection method.

My FPGA IO are not enough to separate the SPI interface for every LMK and LMX devices, so I want to tie them together. 

Thank you very much.

Best Regards.
