24bit Audio CODEC in 130nm~14nm

Overview

This IP is a low power, high quality stereo CODEC designed for portable digital audio applications.
The device integrates complete interfaces to 2 stereo headphone or line out ports. External component
requirements are drastically reduced as no separate headphone amplifiers are required. Advanced on-chip
digital signal processing performs graphic equaliser, 3-D sound enhancement and automatic level control for
the microphone or line input.
This IP can operate as a master or a slave, with various master clock frequencies including 12 or 24MHz for USB devices, or standard 256fs rates like 12.288MHz and
24.576MHz. Different audio sample rates such as 96kHz, 48kHz, 44.1kHz are generated directly from the master clock without the need for an external PLL.
