Note: The crystal X1 mounted on the EM board is a 16.000 MHz crystal, with ±10 ppm initial
tolerance, ± 10 ppm drift over temperature and a temperature range of -10˚ C to +60˚ C. The
crystal is designed for 16 pF load capacitance. In an actual application, the tolerance, drift
and temperature range of the crystal must be considered with application requirements in
mind. Please consult the data sheet and SmartRF
to choose a larger crystal package to save cost. The crystal should have an ESR of 60 Ω or
less.

Power supply section
The power supply section is configured by moving the jumpers located on the board. There
are three voltage regulators on the board, one for use by the FPGA, a 3.3 V regulator for
general use and a 1.8 V regulator for powering the CC2420. The voltage regulator for the
