CC1190 Pin 1 via keep out area

Other Parts Discussed in Thread: CC1101, CC1190

I've just completed a design based on the CC1101 + CC1190 evaluation module. One thing I didn't notice until the gerbers were sent off for PCB manufacturing was that the CC1190 datasheet shows a via keep out area between pin 1 and 16. Of course I put a via in this exact area and the boards are being manufactured.

  Could someone give me more information about this keep out area? Specifically I'd like to know what the effects a via being in that location would cause?

  Thanks!

    The information about the RGV packet included in the datasheet is generic. If you read the fine print on the thermal information drawing some products have a pin 1 indicator in metal which require a keep-out. But CC1190 is not one of the products using this metal indicator and you don't need to use a keep out here. Our reference design don't use a keep-out.

    Thanks very much TER! Good to know. The reference design doesn't have a via there (though probably not because of the RGV pin 1 note) so I wanted to ask.
