Note: CVHD-950-### is a 4 pin part but with 200 mil pin s pacings. So pin
mapping from 6 pin (schematic) to 4 pin footprint is:
1 --> 1, 3 --> 2, 4 --> 3, 6 --> 4
This arrangement also allows for many differential VCXOs to also be used
Assembly Note
ZZ1 U2 and U7: 4 pin and 6 pin footprints are compatible
