How to cascade multiple serially controlled ICs to 1 uC

Hi Everyone,

 

Any one have an example circuit of how to cascade multiple serially controlled ICs such as the HMC1119LP4ME or a PLL chip HMC832ALP6GE with three lines (CLK, DATA, LE)  to a singel micro-controller ?.  Is it as simple as making DATA/CLCK common to both and then just using two seperate I/Os for LE to switch between them when programming them ???

 

Thanks
