SC14CVMDECT SF Cordless Voice Module
© 2012 Dialog Semiconductor B.V. 28 July 1, 2014 v1.6
Re-certification of the SC14CVMDECT SF is required if
at least one external antenna is added. On request,
Dialog Semiconductor can provide a pre-certified PCB
layout for an external antenna circuit.
RF1 is also recommended to use and can be con-
nected to the RF cable to be able to do the JPN DECT
type approval test.
4.13.1 Internal antenna only
The FAD function is not enabled if only the internal
antenna is used. In this case pins RFP0, RFP0n, P0
and P0n must be left unconnected.
4.13.2 Internal and external antenna with FAD
Figure 28 shows one external antenna that is con-
nected to RF1 of the SC14CVMDECT SF. This config-
uration supports the FAD function. In this case pins
RFP0, RFP0n, P0 and P0n must be left unconnected.
The software patch code is not needed if the
SC14CVMDECT SF is operated as FP.
