as possible to the pins and should have a low-resistance and low-inductance
connection to ground to achieve the best performance.
The crystal (XTAL), the two load capacitors (CX1, CX2), and the internal circuitry
connected to pins XTAL1 and XTAL2 form the crystal oscillator. To achieve the best
accuracy and stability of the reference frequency, large parasitic capacitances should
be avoided. Crystal lines should be routed as short as possible and not in proximity of
digital I/O signals. This is especially required for the High Data Rate Modes; refer to
section 7.1.4.
Crosstalk from digital signals to the crystal pins or the RF pins can degrade the system
performance. Therefore, a low-pass filter (C3, R1) is placed close to the CLKM output
pin to reduce the emission of CLKM signal harmonics. This is not needed if the CLKM
pin is not used as a microcontroller clock source. In that case, the output should be
turned off during device initialization.
The ground plane of the application board should be separated into four independent
fragments: the analog, the digital, the antenna, and the XTAL ground plane. The
exposed paddle shall act as the reference point of the individual grounds.
Please note that pins DIG1, DIG2, DIG3, and DIG4 are connected to ground in the
Basic Application Schematic; refer to Figure 3-1. Special programming of these pins
requires a different schematic; refer to section 3.2.
