BU8733KV General Description
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, / 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.
BU8733KV Features
1) 3V single power supply (VDD = 2.7V to 3.3V).
2) Built-in 14-bit precision linear, / A-LAW codec.
3) Transmission filter for the codec unit conforms to ITU-T recommendations.
4) Built-in PLL circuit for system clock generation.
5) Tone signal generator contains DTMF signal, scale tone, and variable tone functions.
6) Analog input / output functions:
Built-in mic amplifier.
Built-in receiver speaker amplifier (32? BTL type).
Built-in attenuator for wide gain adjustment range.
Data signal I / O circuit allows for connection to external devices.
For the external output and receiver output, softmute function reduces pop noise when the power is turned on and off.
7) Internal switching transistor for ringer drive.
8) Internal DSP interface circuit supports multiple DSP formats.
