These power-up settings were chosen because both 25 MHz and 156.25 MHz are common SyncE clock
frequencies. Also, the use of Free Run mode means that, at power-up, the EVB will produce an accurate SyncE
clock.
The power up settings for the Si5328 are as follows:
25 MHz input on CKIN1
CKIN2 is not used because of free run mode
25 MHz output on CKOUT1
156.25 MHz output on CKOUT2
Loop BW of 0.085 Hz
LVPECL outputs for CKOUT1 and CKOUT2
