BU8776KN is PCM CODEC deveolped for digital
cellular phones. High-precision linear CODEC and
each audio part are integrated into a single chip by
mixed signal technology. Compact and thin QFN48U
package is adopted.
1) +3V single power supply (V
2) 14bit high-precision linear µ/A-LAW CODEC
3) Transmission filter in CODEC (Based on ITU-T G.714)
4) Built-in PLL circuit for generating system clock
5) Built-in DSP I/F for PDC, N-CDMA
6) Serial I/F for register setting adapted for 3-wire serial type
7) Selectable PCM data transmission clock frequency
8) Wide variety of Analog I/O functions
9) QFN48U small, thin package
