Thank you for visiting Cirrus Logic online. We produce integrated circuits
(chips) for consumer entertainment electronics, automotive entertainment and
industrial product applications.
Please note that we do not manufacture PC video cards, PC audio cards or
modems, and we do not support these products. If you are seeking support for a
PC audio or video product or a PCMCIA card, you must contact the manufacturer.
We will not be able to assist you.
If you don't know the manufacturer of your Cirrus- or Crystal-based product
(Crystal Semiconductor was purchased by Cirrus Logic in 1991), you can locate
your manufacturer through the Federal Communication Commission (FCC) number,
which should be printed on the card itself. This number will appear with FCC ID
and the # sign followed by a 17-digit number. The first three characters are all
that you need to find your manufacturer; search the FCC database at www.fcc.gov/oet/fccid/.
As a convenience to you, we offer an archive of all our available generic
audio and Ethernet drivers at www.cirrus.com/en/support/drivers/index.html.
We do not provide end-user driver support, and we do not take responsibility for
the performance of any drivers, which may have been modified for individual
products by the product manufacturer.
In order to use these generic drivers, you need to know the Cirrus or Crystal
brand part number your audio or Ethernet subsystem is based on. If you do not
know the part number, contact the manufacturer of your bundled PC for that
information and additional support.
Our line of modem products is now owned and supported by Intel. Please
contact them at www.intel.com if you need
drivers or support for a modem product.
If you purchased an Intel motherboard that uses a Crystal chipset and need
driver or installation help, call Intel Tech Support at 1-800-628-8686.
The company that owned our graphics technology (ISDCorp) is no longer in the
graphics business. If you need graphics drivers, www.video-drivers.com has some drivers for
our old graphics chips.
If you are seeking Windows-based audio drivers, visit the Microsoft Web site
(www.microsoft.com) and do a Search. In many
cases, the drivers are available on this Web site.
If none of the above addresses your needs, you might try www.driverguide.com; they have many Cirrus
Logic drivers listed.
We hope that this information will prove useful to you.
