I2S Codecs

General Description

The I2S family of low-powered, high-fidelity integrated CODECs is targeted at a wide variety portable applications such as wired and wireless portable audio accessories, EPCs (Embedded PCs) / Industrial IoT / SBCs (Single Board Computers) and Voice Activated Assistants / “Smart Speakers”. In addition to a high-fidelity low-power CODEC, some of the I2S family devices offer up to 3W Stereo or Mono DDX™ Class-D speaker integrated amplifiers, a ground-centered referenced true capless headphone amplifier, highly flexible digital audio inputs and outputs with support for I2S / LJ / RJ / Bluetooth Linear PCM format with Gain Code support as well as both Intel and Traditional TDM, and up to four programmable system PLLs to enable the timing management of the systems applications processor, USB interface, secondary audio and other subsystems. Beyond high-fidelity for portable systems, the family of devices offer an enriched “audio presence” through built-in digital signal processing capability which is easily configured using the Tempo ASC Windows-based GUI.
