AD1974 Daisy Chain

1) Regarding the AD1974, the data sheet mentions that 16 channels are supported. However, the example of daisy chaining the AD1974 only shows two addition devices - is it in fact possible to connect 4 x AD1974 together?

2) If 4 devices are supported, how are they connected, are there any example schematics etc?

3) Can a single 12.288mhz oscillator drive all the clocks directly and support 48khz sampling rate for all 12-16 channels?

4) Finally, the data sheet shows the connection with a Sharc with ABCLK going to both TxCLK and RxCLK. Why is does it need to go to TxCLK?
