RFW-D100 ARCHITECTURE
RFW-D100 DESCRIPTION
Oscillator Characteristics
The oscillator module can be used as the source of
clock to the RFW-D100. It is a stand alone module that
can be bypassed. Optionally, an external oscillator can
drive the RFW-D100, since the CLK1 pin is a primary
clock input to the RFW-D100. When the oscillator
module is used, its output SYSTEM_CLOCK should
be connected to the RFW-D100 primary clock input
CLK1. Here, the oscillator module controls the
RFW-D100’s working modes: power down, idle mode,

and working mode. The oscillator module input pins
[POWER_DOWN(40),
IDLE_RESET(38)] determine the working mode.
The oscillator module is connected to the external
crystal through pins OSC_I and OSC_IO in pierce
topology as shown in Figure 4. C1, C2, and Rd should
be set according to the type of the crystal. Rfeb should
be around 1 MO. The crystal frequency can be
between 6 ⇔ 24 MHz.
