SLES220B – JUNE 2009 – REVISED FEBRUARY 2010
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,
and can be selected by the value of the FREQ_ADJ resistor connected to AGND in master mode.
For slave-mode operation, turn off the oscillator by pulling the FREQ_ADJ pin to VREG. This configures the
OSC_I/O pins as inputs, which 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 accompanying audio-source ground. A local ground
area underneath the device is important to keep solid to minimize ground bounce.
Netlist for this printed circuit board is generated from the schematic in Figure 14.
Note T1: PVDD bulk decoupling capacitors C60–C64 should be as close as possible to the PVDD_X and GND_X
pins; the heat sink sets the distance. Wide traces should be routed on the top layer with direct connection to the pins
and without going through vias. No vias or traces should be blocking the current path.
Note T2: Close decoupling of PVDD with low impedance X7R ceramic capacitors is placed under the heat sink and
close to the pins.
Note T3: Heat sink must have a good connection to PCB ground.
Note T4: Output filter capacitors must be linear in the applied voltage range, preferably metal film types.
