PRODUCTION DATA
The PCM1809 signal chain is comprised of very-low-noise, and low-power analog blocks and highly flexible and configurable digital processing blocks. The high performance and flexibility combined with a compact package makes the PCM1809 optimized for a variety of end-equipments and applications that require multichannel audio capture. Figure 6-9 shows a conceptual block diagram for the PCM1809 that highlights the various building blocks used in the signal chain, and how the blocks interact in the signal chain.
Configurable high-performance multistage digital decimation filter sharply cuts off any out-of-band frequency noise with high stop-band attenuation.
