Overview
w WM8973L Stereo CODEC for Portable Audio Applications DESCRIPTION The WM8973L is a low power, high quality stereo CODEC designed for portable digital audio applications.
The device integrates complete interfaces to stereo or mono microphones and a stereo headphone.
External component requirements are drastically reduced as no separate microphone or 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.
The WM8973L 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.
The WM8973L operates at supply voltages down to 1.
8V, although the digital core can operate at voltages down to 1.
42V to save power, a...
