JAJSDI7B July 2017 – October 2018 TAS2505-Q1
The TAS2505-Q1 implements signal-processing capabilities and interpolation filtering through processing blocks. These fixed processing blocks give users the choice of how much and what type of signal processing they may use and which interpolation filter is applied.
The choices among these processing blocks allows the system designer to balance power conservation and signal-processing flexibility. Table 2 gives an overview of all available processing blocks of the DAC channel and their properties. The resource-class column gives an approximate indication of power consumption for the digital (DVDD) supply; however, based on the out-of-band noise spectrum, the analog power consumption of the drivers (AVDD) may differ.
The signal-processing blocks available are:
The processing blocks are tuned for common cases and can achieve high image rejection or low group delay in combination with various signal-processing effects such as audio effects and frequency shaping. The available first-order IIR and biquad filters have fully user-programmable coefficients.
