ALC260(D)
Datasheet

General Description
The ALC260 and ALC260D* 2-Channel High Definition Audio (HDA) Codecs with UAA
(Universal Audio Architecture), featuring a 24-bit two-channel DAC and two stereo 20-bit
ADCs, are designed for commercial Desktop and Notebook PC systems. The codecs
incorporate proprietary converter technology to achieve 95dB sound quality; easily meeting
PC2001 requirements and also bringing PC sound quality closer to consumer electronic
devices.
The ALC260(D) provides 2 output channels, along with flexible mixing, mute, and fine gain
control functions to provide a complete integrated audio solution for PCs. The DAC (with a
highest sampling frequency of 192kHz) was previously only implemented in high-end
consumer electronics, but is now achieved by PCs equipped with the ALC260(D). The
ALC260(D) provides high-quality audio using S/PDIF to output analog data, or for
multiple-source recording applications.
Realtek’s proprietary impedance sensing and jack detect techniques allow device loads on
inputs and outputs to be auto-detected. All analog IO are input and output capable,
headphone amplifiers are also integrated at each analog output. All analog IOs can be
re-tasked according to user’s definitions, or automatically switched depending on the
®
connected device type (Universal Audio Jack
).
The ALC260(D) supports 32-bit S/PDIF input and output functions and a sampling rate of up
to 96kHz, offering easy connection of PCs to high-quality consumer electronic products such
as AC-3 decoders/speakers, and mini disk devices.
The ALC260(D) supports host/soft audio from the Intel ICH6 chipset, and also from any
other HDA compatible audio controller. With power management setting, Realtek’s unique
®
microphone application (AEC/Beam Forming/Noise Suppression), optional Dolby
Digital
Live, and reliable driver support, the ALC260(D) is the ideal choice for Commercial
Desktop and Notebook PC users.
®
Note: ‘D’ directly after ALC260 indicates Dolby
Digital Live (software feature). See Table 83, page 72.
