Communication ICs  
Linear codec IC for digital cellular tele-  
phones  
BU8730KV  
The BU8730KV is a linear codec IC developed for use with digital cellular telephones. It contains a 14-bit precision linear  
codec and various other analog input / output features.  
Also, there is a built-in DAI and many tone signal functions making this IC perfect for use with GSM cellular telephones.  
FApplications  
Digital cellular telephones  
FFeatures  
1) )3V single power supply (VDD = 2.7V to 3.3V).  
2) Low current consumption of 8.2mA (typ.) when fully  
operating and 20 µA (max.) when powered down  
(VDD = 3V).  
8) Analog input / output functions:  
S Built-in mic amplifier with gain switching capabili-  
ties.  
S Data signal I / O circuit allows for connection to ex-  
ternal devices.  
3) Built-in 14-bit precision linear codec.  
4) Transmission filter for the codec unit conforms to  
ITU-T recommendation G.714.  
S Receiver output, ringer output, and EXT output are  
soft mute compatible.  
5) DTMF signal, GSM triple tone, and scale tone signal  
generator functions are built into the tone signal gen-  
erator block.  
9) Internal DAI (digital audio interface) with GSM11.10  
support.  
10) Internal DSP interface circuit supports multiple DSP  
formats.  
6) Signal generator and output level adjustment circuits  
are built in with the sounder output functions.  
7) Built-in PLL circuit for system clock generation.  
11) VQFP 48-pin package.
