HMC4069:Output signal unlocked

Hi! I am using HMC4069 to get a 80M wave. I have an input of 10M wave and set the A0-A4 as 11100 (8). The type of the VCO is CVSS-945-80.000, which has a Kv value of 2kHz/V. It means it can only be tuned in a narrow band. Based on this Kv value, i make the PLL SIM in the ADISimPLL and the design file would be attached. Are there any mistakes i made during the design? Thanks for your help.
