DESCRIPTION
A powerful 3-channel audio filter and effects system-on-a-chip
designed for seamless insertion in an audio serial digital data
path. The QF3DFX is easily configured using the Quickfilter’s
QFProTM Design Software (QFPro) with royalty free user
tunable advanced audio algorithms for psychoacoustic effects.
The QF3DFX can be configured to interface with I2S or TDM
based audio systems. The QF3DFX can operate over a broad
range of data rates up to 48ksps and can support data
resolutions of 16 or 24 bits. The QF3DFX is self-booting and
provides pin control for volume up, volume down, mute and
profiles supporting cost sensitive designs with minimal external
requirements. The QF3DFX automatically powers down when
audio data is not present.
