Figure 4 shows a typical application using a CE6313 as a demodulator. This is available as a reference design
(CE9541) from Intel Corporation.
The design uses a standard two layer board. All components are mounted on the upper surface with the lower
surface as a ground plane. The RF input does not require any external matching components although a coupling
capacitor is required. The RF bypass output requires a series inductor for optimum matching. Good decoupling
should be used - these components should be mounted as close to the device as practicable.
All ground contact to the CE5039 is to the ground ‘paddle’ on the underside of the package. This must be soldered
fully to the board to achieve best thermal and electrical contact. It is recommended that an array of vias (4 x 4) is
used to achieve good contact to the ground plane underneath the device
A common crystal reference can be used for the tuner and demodulator. The crystal oscillator capacitors are
optimised for a 10.111 MHz reference.
Sensitivity is optimised by minimizing interaction from digital signal activity in the demodulator. This is achieved by
filtering in the agc control, and filter networks in the baseband I and Q signals between the demodulator and
CE5039. These networks should be mounted as close to the CE5039 as possible.
The typical performance from the reference design is shown in the table below:
