PCM codec IC for digital cellular
telephones
BU8733KV
The BU8733KV is a PCM codec IC developed for use with digital cellular telephones. The BU8733KV contains analog
input / output features such as a 14-bit linear precision,
µ
/ A-LAW codec, mic and speaker amplifiers, and a switching
transistor for the ringer drive. Also, there is a built-in DSP interface circuit for support of multiple DSP formats making
this IC perfect for use with PDC cellular telephones.
