Description
The CRD4630-10 is a low cost PCI add-in board refer-
ence design that showcases Cirrus Logic's six channel
audio capabilities. The board contains three stereo out-
puts for front L/R, surround L/R, and center/low
frequency (LFE) speakers. The card features a CS4630
controller, CS4297A primary audio codec and CS4294
secondary audio codec. The audio codecs include ste-
reo 20-bit DACs and stereo 18-bit ADCs.
The CRD4630-10 reference design is available by or-
dering the CMK4630-10 manufacturing kit. Use this kit
to help you develop high quality PCI add-in cards and
PC motherboard audio designs. The CMK4630-10 in-
cludes a full set of schematic design files (OrCAD
format), PCB job files (PADS
files, and bill of materials. This design is production
ready and can easily be modified to meet your specific
requirements.
