Introduction

SLES115 — August 2004
TAS5518
Similarly, the TAS5518 carries additional precision in the form of overflow bits to permit the value of
intermediate calculations to exceed the input precision without clipping. The TAS5518 advanced digital audio
processor achieves both of these important performance capabilities by using a high performance digital audio
processing architecture with a 48-bit data path, 28-bit filter coefficients, and a 76-bit accumulator.

Input Crossbar Mixer
The TAS5518 has a full 8x8 input crossbar mixer. This mixer permits each signal processing channel input
to be any ratio of any of the eight input channels. The control parameters for the input crossbar mixer are
programmable via the I2C interface. See the Input Mixer Register (0x410x48, channels 18) section.
