Déesse is a DSP + High Quality AUDIO PCI card designed for all PCI computers

It supports the PCI 2.1 protocole at 33 MHz with 3.3V I/O (LVTTL) with 5V tolerance.

It is based on two sub-systems :

- a DSP system based on the MOTOROLA DSP56301

- an AUDIO system based on the TI TLC320AD77C

The DSP56301 is based on the powerful DSP Engine DSP56301 Core capable of executing an instruction on every clock cycle, thus yielding a twofold performance increase as compared to the 56000 Core while maintaining object code compatibility with it.

The TLC320AD77C is a stereo analog-to-digital (A/D) and digital-to-analog (D/A) 24-Bit delta-sigma converter with excellent audio performances of 100dB.

It has a wide range of sampling rates starting from 16 kHz to 96 kHz with 16-, 20-, or 24-Bit input/output data.
