PCM CODEC (general pronunciation arranges decoding chip) the product
OKI provides each kind of data transfer rate the ADPCM/PCM pronunciation to arrange the decoding chip (ADPCM/PCM CODEC), supports ITU-T the G.726 standard coding form, the G.711 A-Law/μ-Law coding form and the uniform encoding form, the power loss is low, the use scope is broad.
Main application field is included:
(1) telephone system: IP telephone, traditional telephone, handset, intercom, PBX, PABX, MODEN, gateway, line card and so on. (2) peaceful against system: Has pronunciation function An Fang the system. (3)DVR: Has the pronunciation to record the function DVR. (4) records digital products and so on pen.
