Ten, Eight and Six Channel HD Audio Codecs

Overview

The current errata and updates for the revision B2 are described below. These items were gathered through

evaluation, if additional items are identified, notice will be given. Device reliability, life span, and suitability for

intended use are not affected. Product covered by this errata carry standard guarantee and warranties.

Product Summary

Product can be identified in several ways. The main part number is located below the IDT Name on the physical

chip top marking. The revision code is the first two digits of the fourth line of marking. Products can be identified

specifically through the software accessible registers as indicated in the table below. It is recommended that

software programmers incorporate identification and adjustment code for the device revisions when updating

drivers.

Dynamic Range: Headphone ports with 10k loading have a recommended external filer of 5ohms/22nF.

With the new WLP requirements, using an external 27nF capacitor or other value is acceptable. Please

note that you may have to be "tune" the system for optimal DR behavior by changing this external

capacitor during DTM certification. It has no actual effect on audio performance and is only done to

compensate for the AP test equipment.

Issue Date

Production Status

Please note there are no additional known issues or errata items at this time.

Noise may be

heard when

running digital

microphone at or

below the

standard clock

rate (2.58MHz)

with the total

record gain +

boost > ~20dB.

May experience

clipping and/or

distortion at -1dB

signal levels.

Description

Issue

Option 1. Run digital microphones using the 3.528MHz

clock rate (may require a waiver from certain DMIC vendors

whose parts are rated with a max clock value below

3.528MHz). This option is implemented with a simple BIOS

widget write and does not require any hardware or driver

changes.

Option 2. Disable the hardware gain inside the driver and

implement the boost/gain in SW. This option will require a

driver spin, and it will limit the total mic gain to 30dB.

Additionally, this option is not available when using the MS

Class Driver (which will expose the hardware gain).

These devices are not offered with a productized 3.3V

Analog option. If customer chooses to run the device as

3.3V, please note that material will not be ATE tested at

that level and this errata may apply.
