5 Application Circuits
5.1 Basic Application Schematic
A basic application schematic of the Atmel AT86RF232 with a single-ended RF
connector is shown in Figure 5-1 . The 50Ω single -ended RF input is transformed to the
100Ω differential RF port impedance using balun B1. The capacitors C1 and C2 provide
AC coupling of the RF input to the RF port, optional capacitor C4 improves matching if
required.

The power supply decoupling capacitors (CB2, CB4) are connected to the external
analog supply pin 28 (EVDD) and external digital supply pin 15 (DEVDD). Capacitors
CB1 and CB3 are bypass capacitors for the integrated analog and digital voltage
regulators to ensure stable operation. All decoupling and bypass capacitors should be
placed as close 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.
