I was planning to design in the M10578-A3 (or similar) to discipline a 10MHz OCXO. Unfortunately my design has a 1600MHz signal used throughout the product. While this signal would not be deliberately routed to the PCB containing the GPS module, it would of course always be present at a low level. Probably the lowest I could guarantee the 1600MHz signal would be -80dBm, and even that would take some doing.
It appears this is in-band to the SAW filter and LNA, which would seem to generally preclude the use of a GPS receiver in this product at all. While I see "AIC, Active Interference Cancellation" referred to in the datasheet I have no idea if this is any help for my application.
