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.
Applications
Digital cellular telephones
Features
3V single power supply (V
DD
= 2.7V to 3.3V).
2) Built-in 14-bit precision linear,
μ
/ 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).
1)
Built-in attenuator for wide gain adjustment range.
Data signal I / O circuit allows for connection to ex-
ternal devices.
For the external output and receiver output, soft-
mute 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.
Absolute maximum ratings (Ta = 25 C)
