The VREG pin is not recommended to be used as a voltage source for external circuitry.
OSCILLATOR
The oscillator frequency can be trimmed by external control of the FREQ_ADJ pin.
To reduce interference problems while using a radio receiver tuned within the AM band, the switching frequency
can be changed from nominal to lower values. These values should be chosen such that the nominal and the
lower-value switching frequencies together result in the fewest cases of interference throughout the AM band.
Switching frequencies can be selected by the value of the FREQ_ADJ resistor connected to AGND in master
mode.
For slave-mode operation, turn of the oscillator by pulling the FREQ_ADJ pin to VREG. This configures the
OSC_I/O pins as inputs and must be slaved from an external clock.
PRINTED CIRCUIT BOARD RECOMMENDATION
Use an unbroken ground plane to have a good low-impedance and -inductance return path to the power supply
for power and audio signals. PCB layout, audio performance and EMI are linked closely together. The circuit
contains high, fast-switching currents; therefore, care must be taken to prevent damaging voltage spikes. Routing
of the audio input should be kept short and together with the accompanied audio source ground. It is important to
keep a solid local ground area underneath the device to minimize ground bounce.
Netlist for this printed circuit board is generated from the schematic in Figure 14.
