Im using a board with AD9548 connected to an GPS retriever. I was able to successfully configure the device to get the 122.88Mhz output frequency, and i config out0 to 1hz，cmos， 24mA, and i read the register：0x0D0A， the value is 0x32，it means Freq lock ，and phase lock,
And set register：0x0402 = 0x20， 0x0403 = 0x02， 0x0507 = 0x07，,but，I see no synchronize from the oscilloscope，
The phase of 1Hz is 3μs with GPS Phase difference，and the phase offset seems not a stable value, sometime is 500 ns,
do you have some way to solve it?
