Dell's laptops Inspiron 3500, Inspiron 3501, Inspiron 3505 are using Cirrus Logic CS8409 HDA bridge with CS42L42 companion codec. The CS8409 is a multichannel HD audio routing controller. CS8409 includes support for four channels of digital microphone data and two bidirectional ASPs for up to 32 channels of TDM data or 4 channels of I2S data. The CS8409 is intended to be used with a remote companion codec that implements high performance analog functions in close physical proximity to the end-equipment audio port or speaker driver. The CS42L42 is a low-power audio codec with integrated MIPI SoundWire interface or I2C/I2S/TDM interfaces designed for portable applications. It provides a high-dynamic range, stereo DAC for audio playback and a mono high-dynamic-range ADC for audio capture CS42L42 is connected to CS8409 HDA bridge via I2C and I2S.
