The ARCOFI-SP PSB 2163 is a high performance codec filter device with a state of the
art tone generator and an excellent speakerphone implementation. To obtain the full
performance of the device, some care in designing the analog circuitry and the printed
circuit board has to be taken. This application note gives some hints and wants to
provide understanding of the parameters that influence the performance.
With "performance", especially the following effects are meant:
• Signal to noise ratio, especially in transmit direction (analog to digital)
• Idle channel noise (the noise that is present when there is no signal applied)
• Spurious oscillations
• Sensitivity to any kind of interfering signals (noise on power supply, RF interference,
The ARCOFI-SP contains high performance A/D and D/A converters with more than
16bit resolution in order to allow the different signal processing steps without
degradation of the signals themselves. On one silicon the PSB 2163 integrates a high
gain, analog preamplifier, the converters as well as an digital signal processor. Besides
the ARCOFI-SP is used in an digital environment that typically causes noise on the
power supply and produces many kinds of interfering signals. For all these reasons,
careful grounding, decoupling, and shielding is the key to get best system performance.
