Hi all,

 

I have the questions for HMC704 PLL register setting sequence.

 

1.After POR, how long is the wait time , accessing the register to read/write ?
Data sheet describe "All chip registers will be reset to default states approximately 250 us after power up of DVDD."
Is it 250 us + @ ?

 

2.Similarly , after soft reset how long is it ?

 

3.How long is the interval time to write the register continuously , between Reg 0(x)h and Reg 0(x+1)h ... Reg 0(x+n)h ?
Or no need the interval time ?

 

4.Is it available to write the necessary registers only ?
For example, when using the integer mode, writing/setting the Reg 00h, 01h, 02h, 03h, 06h, 07h, 08h, 09h, 0Bh, 0Fh only ?

 

5.Are there restrictions or sequence for writing/setting the Reg ?

 

Best regards,
sss
