CODEC IC for digital mobile phone
BU8732AKV
BU8732AKV is a PCM codec IC for digital cellular phones. This includes plenty of analog input / output functions such as
a 14bit precision linear.
µ
/ A-LAW codec, a microphone amplifier with two systems, amplifiers for speaker and earphone
and a switch transistor for driving a ringer. This IC is the most suitable for both PDC system and CDMA system cellular
phones.
Application
Digital cellular phones with CDMA system, Digital cellular phones with PDC system.
Features
1) +3V single power supply. (V
DD
=2.7 to 3.3V)
2) 14bit precision linear
µ
/ A-LAW codec.
3) Transmission filter of the codec block is in conformity to the ITU-T recommendation G. 714.
4) Built-in PLL circuit for system clock generation.
5) Built-in DSP I/F which is in conformity with PDC and N-CDMA.
6) Arbitrary setting of the clock frequency of PCM data transmission is allowed :
µ
/ A-LAW
64kHz to 2048kHz
Linear
128kHz to 2048kHz
7) Plenty of input / output analog functions :
Two systems of built-in microphone amplifier (differential input type, single input type)
Built-in speaker amplifier for receiver (32Ω BTL type)
Built-in speaker amplifier for earphone (32Ω single type)
Built-in speaker amplifier for REXT of call receiving system (600Ω)
Built-in electronic volumes for gain adjustment. (Call-receiving system, call sending system, TONE system)
Built-in input / output circuit for data signal which allows external connection.
Pop noise of REXT earphone and receiver outputs at the time of switching on and off the power supply is reduced
by means of soft mute.
8) A built-in function to generate DTMF signals and musical scale tones is provided in the tone signal generating block.
9) Built-in switch transistor for driving a ringer.
10) VQFP 48 pin package.
