The HMC1190A data sheet describes RSV15 and RSV24 as "Reserved. These pins are reserved for internal use; leave them floating."
But, on the EVB schematic, it is as follows.
1) RSV15: IF1EN => pull-down
2) RSV24: IF2EN => pull-down, pull-up jumper
The customer wants to use only IF1 but not IF2.
How should I handle RSV15 and RSV24?
Please answer the questions.
