Archband achieves SMIC qualified 96dB Hi-Fi Audio CODEC IP in 65nmLL process

San Jose, CA -- January 10, 2013 -- Archband Inc, a Silicon-Valley based analog mixed-signal IP vendor, today announced the immediate availability of its second generation silicon proven, low power and high performance stereo audio CODEC IP AR82S01 in SMIC 65nmLL logic process.

The company's premium audio CODEC IP has successfully passed SMIC's 3rd-party IP qualification program. The IP delivers 96dB SNR performance and -101dBV total in-band noise with ultra compact size. Such high-end performances are perfectly desirable for SOC companies to make design-wins in HDTV, PMP, MID, TV set-top, IP phone, tablets, Car Audio, and e-Book markets.

The silicon proven CODEC macro IP employs oversampling sigma-delta architecture with optimized ultra low power, low noise and compact design architecture. The CODEC delivers high substrate noise immunity and PSRR, as well as robust performance to process, voltage and temperature variations for SOC application.

The AR82S01 CODEC IP contains stereo analog-to-digital converter (ADCs) and stereo digital-to-analog converters (DACs), featuring with digital and analog microphone and line input peripherals, microphone biasing, headphone and line output peripherals, speaker amplifier, automatic level control (ALC), digital filters, voltage regulators, current sensing, short circuit protection, and thermal protection.

The CODEC IP supports standard digital audio interfaces like I2S, DSP-mode in both master and slave modes, and data programming interfaces such as I2C, SPI, MCU as well. The IP contains on-chip band-gap and voltage reference circuitry to ease system level implementation and reduce BOM cost.

Archband¡¦s audio IPs have been licensed by many customers worldwide since 2003, including top IPO semiconductor manufacturing companies. The company's audio IP family includes 16-24bit audio CODEC, ADC, DAC, and audio peripherals like microphone bias, headphone driver, speaker amplifier, digital microphone interface, PWM controller.

The AR82S01 evaluation board is available to customers. The EVB is single USB-powered with software interface for quick turn-around evaluation. Please contact us for more information.
