APPENDIX—POWERUP AND FACTORY DEFAULT SETTINGS
For the Si5324-EVB, Si5325/26-EVB, and Si5327-EVB, the power up settings are as follows:
19.44 MHz input on CKIN1
CKIN2 is not used because of free run mode
155.52 MHz output on CKOUT1
622.08 MHz output on CKOUT2
Loop BW of 70 Hz (Si5325/26-EVB)
Loop BW of 7 Hz (Si5324-EVB and Si5327-EVB)
LVPECL outputs for CKOUT1 and CKOUT2
For the Si5322/23-EVB, the factory jumper settings are as follows:
