Power-Up/Down sequence of HMC1113, HMC924 & HMC709

Question

Hello, 
 I would like to know power-up/spwn sequence of HMC1113LP5E, HMC924LC5 and HMC709LC5. Are there any recommended power up/down sequence of those prosucts? 
 And, I have one more question about evaluation board of those products. According to the datasheet of those products, the evaluation board are used some materials for the board. e.g. Rogers 4350, Arlon25 and FR4. Are there any different perfomance by the material? 
 And how much different? 
 Best regards,

Hi Akira, 
 For the HMC1113LP5E it should not matter which order the supplies are connected. 
 For the HMC924LC5 please leave Vgg open before connecting Vdd1, Vdd2, Vdd3 and Vdd4 to 5V. 
 Thanks,
