The WM8750 is a low power, high quality stereo codec with integrated stereo or mono microphone interfaces and a stereo headphone. Advanced on-chip digital signal processing performs graphic equaliser, 3-D sound enhancement and automatic level control for the microphone or line input. The WM8750 can operate as a master or a slave, with various master clock frequencies including 12 or 24 MHz for USB devices, or standard 256 fs rates like 12.288 MHz and 24.576 MHz. Different audio sample rates such as 96 kHz, 48 kHz, 44.1 kHz are generated directly from the master clock without the need for an external PLL.
