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 (0x41−0x48, channels 1−8) section.
