Crystal Oscillator
The operation frequency of the W91031 is 3.579545 MHz. Crystal oscillators, ceramic resonators or
other clock sources can be used. A crystal oscillator or ceramic resonator can be directly connected
to the OSCI and OSCO pins without the need for external components. If other clock sources are
used, the OSCI pin should be driven by a clock source and the OSCO pin used to drive other external
clocked devices, or left open. Figure 7-9 shows some applications.

Figure 7-9. Some Application of Clock Driven Circuit
Bias Voltage Generator
The bias voltage generator provides a low impedance voltage source equal to V
DD
/2 and is used to
bias the gain control op-amp. The voltage source is also used for internal circuits. A 0.1
μ
F capacitor
should be placed between the VREF pin and V
SS
to reduce noise.
