DESCRIPTION
The WM8510 is a low power, high quality mono codec designed
for Voice over Internet Protocol (VoIP) and Digital Telephones.
The device integrates support for one pseudo-differential and
one single ended input (Handset Mic and Speaker Mic) and
includes drivers for speakers or headset, and mono line output,
making it ideal for Telephone designs. External component
requirements are reduced as no separate microphone or
earpiece amplifiers are required.
Advanced Sigma Delta Converters are used along with digital
decimation and interpolation filters to give high quality audio at
sample rates from 8 to 48ks/s.
Additional digital filtering options are available in the ADC path,
to cater for application filtering such as ‘wind noise reduction’,
plus 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.
The WM8510 operates at supply voltages from 2.5 to 3.6V,
although the digital core can operate at voltages down to 1.62V
to save power. The speaker and mono outputs use a separate
supply of up to 5V which enables increased output power if
required. Different sections of the chip can also be powered
down under software control by way of the selectable two or
three wire control interface.
WM8510 is supplied in a convenient 28-pin SSOP package,
offering high levels of functionality in easy to use package.
