3)

How are these devices different than the other Crystal PCI audio products

(CS4280 and CS4614)?

A:

The CS4280 does not offer DSP acceleration for wavetable synthesis and

3D sound, using the host processor instead. The CS4614 offers DSP pro-

cessing, but not digital I/O (SPDIF) or ZVPort support.

4)

Which markets would the CS4622 and CS4624 serve?

A:

Manufacturers of PC motherboards, portables, and PCI audio cards

would use the CS4622 and CS4624, where the performance advantages

of DSP processing are desired along with the digital input/output to con-

nect to high-end audio devices . The DSP processor is used for hardware

wavetable synthesis and 3D audio acceleration for the games/multimedia

market, and acoustic echo cancellation for speakerphone/ videoconfer-

encing in the commercial market.
