Typical application
Figure 14
figure does not contain all decoupling capacitance required by the SN260. The Balun
provides the impedance transformation from the antenna to the SN260 for both TX and RX
modes. The harmonic filter provides additional suppression of the second harmonic, which
increases the margin over the FCC limit. The 24MHz crystal with loading capacitors is
required and provides the high frequency source for the SN260. The RC debounce filter (R4
and C7) is suggested to improve the noise immunity of the nRESET logic (Pin 11).
The SIF (nSIF_LOAD, SIF_MOSI, SIF_MISO, and SIF_CLK), Packet Trace (PTI_EN and
PTI_DATA), and SDBG signals should be brought out test points or, if space permits to a 10-
pin, dual row, 0.05-inch pitch header footprint. With a header populated, a direct connection
to the InSight Adapter is possible which enhances the debug capability of the SN260. For
