SmartDV’s I2S Controller IP is a silicon-proven, fully featured Inter-IC Sound solution purpose-built for SoC designs requiring reliable, standards-compliant digital audio connectivity across consumer electronics, automotive, and IoT applications. Compliant with the Philips I2S Bus Specification (revised June 1996), it delivers complete master and slave transmitter and receiver functionality with bidirectional operation through two unidirectional serial data lines, supporting simultaneous audio playback and recording.
Designed for the practical integration requirements of modern digital audio SoC designs, the IP supports Time Division Multiplexed (TDM) formats, configurable 8/16/24/32/64-bit DAC/ADC resolution, and audio sampling rates up to 192 kHz. Its support for I2S format, PCM format, LSB and MSB bit ordering, programmable word select resolution in master mode, programmable delayed capture and driving of serial data, four selectable reference clock sources with programmable clock divider, interrupt-driven or DMA operation, and 64-deep 32-word FIFOs for left/right transmit/receive give consumer, automotive, and IoT SoC teams a production-tested, feature-complete I2S implementation.
Built for design flexibility and silicon efficiency, the IP core is highly configurable for both ASIC and FPGA implementations, with a strong focus on area optimization, power management, and peak performance. Its local clock gating for minimal power consumption and freeze/suspend operation for system debug support enable fast integration and confident design bring-up across a wide range of process nodes.
