MAXIMUM RATINGS
PCM CODEC
Description
The PCM Codec comprises complete AD and DA channels, including direct interface to the microphone and earphone. The Codec
SNR specification is adjusted to accommodate the Dynamic Range of companded signals used in the target application,
guaranteeing at the same time a comfortable level of idle channel noise.
Both Receive and Transmit channels feature filtering functions and programmable gain. The transmit channel includes an anti-
aliasing filter function in the microphone amplifier to eliminate high frequency signal components that would affect the AD
conversion by being aliased to the voice band.
In the Receive channel, a smoothing filter is included to reduce the out-of band power present at the earphone Amplifier (EA)
output.
The Codec includes sidetone processing, to release the host controller from external signal processing and microphone bias
voltage generation. The gain in both channels is controlled using two segments for flexibility, a coarse gain implemented in the
analog block (EA and MicA) and a fine gain implemented in the digital block to allow precise tuning of amplitudes.
