Hello Colleagues,

 

I am planning to use AD9552 to generate the clock signal for our radio transmitter. The clock reference of AD9552 can be a crystal unit or the input reference signal. From the evaluation board user guide it is clear that the crystal signal can be passed out from the test port through setting the bit 3 of 0x17 register. My question is, is it possible to pass the input reference signal or the reference signal the chip is now choosing out from the test port(PLL Locked Pin) or from any output pin, for example, from OUT2?

 

Sincerely yours,

Qipeng Cai
