Would like to know about Gain using SYNC-ON-GREEN INPUT

Category: Datasheet/Specs
Product Number: AD9887A

Hi , 

I would like to know about analog input Absolute max for RAIN/GAIN/BAIN/SOGIN as the datasheet states VD - 0.0V 

When we use SYNC-ON-GREEN INPUT as per Figure 8 the input will be negative input in this case the Absolute maxium rating as well as the rating on Table 4  0.0 V to 1.0 V . 

Could you please let me know with regards to the rating on RAIN/GAIN/BAIN/SOGIN  and the absolute rating for these pins . 

I do understand this device is not recommended for new devices. 

Thanking you 

With regards
