CMI9739A - 6-Channel Audio Codec

Download the CMI9739A datasheet PDF. This datasheet also covers the CMI9739_C variant, as both devices belong to the same 6-channel audio codec family and are provided as variant models within a single manufacturer datasheet.

Description

Universality CMI9739 is a 6CH AC97 CODEC, applicable for major MB chipsets of Intel, VIA, Ali, and SIS.

CMI9739 is ideal for PC2001-compliant desktops, notebooks, and home entertainment PCs where high-quality audio is a must.

Features

  • Intel AC’97(Rev 2.2) compatible, meeting Microsoft’s PC2001 requirements.
  • Built-in earphone buffer and internal PLL, the latter saving additional crystal.
  • Earphone buffer, optional on HP_OUT pins(9739) or LINE_HP_OUT pins(9739A).
  • Line-in/rear out share the same jack.
  • Center/bass share the MIC jack.
  • Digital S/PDIF IN/OUT support.
  • 48 LQFP package.
  • CRL 3D: HRTF based DS3D compatible audio engine.
  • EAX 1.0 & 2.
