ADAU1401A - Connecting external slave mode codecs

Hello all,

I am considering the possibility of using the ADAU1401A in my project.

I wish to use several external codecs with I2S bus. the codecs are in slave mode.
I've noticed the ADAU1401A serial input port works only in slave mode, while the output serial port can be configured as master or slave:

I believe this configuration is addressed on the ADAU1401A data sheet, page 45:


I would like to verify if I correctly understood the way the codecs should be connected to the DSP in this configuration:


Is this the right way to do it?
Second, do I have to use a clock buffers for this configuration, or the output BCLK, LRCLK can safely drive the load of several codecs inputs?
Many thanks!
