Hi,

My customer has a question about ADL5350. In datasheet, PIN7 NIC (No Internal Connection) is recommended to be tied ot GND. In EVB schematic, it is left floating. Customer connects PIN7 to GND but ADL5350 doesn't work. After cutting the line off, it turns normal.
I'd like to know if PIN7 should be left floating or tied to GND, or if something else goes wrong.

Thanks a lot!
