This invention relates to detectors and particularly to pulse code modulation (PCM) detectors for recovering synchronous PCM data from a communications channel in which the PMC data is time division multiplexed (TDM) with analog data. A representative application of the invention is for recovering a...
Below is customer's block diagram. There is a 2ch PCM SLIC for FXS and an audio subsystem supports headset and microphone which they don't must need in LM49370. Also, they need TDM. Is LM49370 a good one or could you please suggest a proper solution? Thanks. ...
