BTRESn
The routing of BTCLK_IN should be done with extra care, i.e to avoid noisy
signals. It is crucial that the reference clock supplied to BT is free of
noise to be able to guarantee a good radio performance.
Especially cross talks from surrounding digital signals must be avoided.

'VSS_RF' should be separated from other VSS,
with a clearance of min 0.2mm, on the top layer,
first and second internal layer.
The 'VSS' of the B-BPF and the BT antenna should also be
connected to this 'VSS_RF.'
