Inter-IC Sound Bus Controller (I2S)

A configurable single- or multi-channel Inter-IC Sound (I2S) bus interface controller, combines functions of both transmitter and receiver. The I2S IP can be used in various standard bus-based microprocessor systems, as various bus wrappers such as the ARM® AMBA® interface are provided. 

Benefits

  • Meets Philips ® Inter-IC Sound Bus Specification
  • Supports various modes: I2S Philips Left or Right Justified, DSP, and time-division multiplexing (TDM)
  • Provides two clock domains: host side clock domain and system clock for the I2S channel

Cadence® Inter-IC Sound Bus Controller (I2S) IP includes both single-channel (I2S-SC) and multi-channel (I2S-MC) IP designs. It can be  targeted at ASIC and FPGA implementations, and used in a variety of different applications, such as connecting Analog-to- Digital and Digital-to-Analog converters with very low jitter, error correction for compact disc and digital recording, or digital signal processing. The Cadence Multi-Channel Inter-IC Sound Bus Controller IP can be used in user applications which require multiple channel audio data transmission, as well as in multimedia systems in general.
