The WM8510 is a low power, high quality mono codec with integrated support for one pseudo-differential and one single-ended input (handset mic and speaker mic), and includes drivers for speakers or headset. Separate microphone or earpiece amplifiers are not required. Advanced Delta Sigma converters are used, along with digital decimation and interpolation filters, to give high quality audio at sample rates from 8 to 48 kHz. Additional digital filtering options are available in the A/D converter path to provide application filtering such as ‘wind noise reduction.’ An advanced mixed-signal ALC function with noise gate is provided. An on-chip PLL is provided to generate the required Master Clock from an external reference clock. The PLL clock can also be output if required elsewhere in the system. Different sections of the chip can be powered down under software control by way of the selectable two or three wire control interface.
