AK2308LV

SPEECH CODEC for Digital Key telephone

GENERAL DISCREPTION

FEATURES

AK2308LV is an integrated LSI with PCM CODEC,

Voice path control, MIC amplifier and Handset driver

suitable for PBX/KTS digital key telephone, VoIP

Telephone Analog Interface.

2 MIC AMP for the handset and microphone are

integrated.

Differential driver for the 32ohm speaker and 10k

ohm driver for the handset receiver.

Path control and volume control via serial CPU

I/F

PCM CODEC is compliant to ITU G.711 G.712

specification, very low noise, and low power

dissipation CODEC. A-law and u-law selectable

through Serial I/F register. PCM I/F provides

Long/Short frame format. The output is 8bit

compressed data along with 16bit linear format. FS

must be 8kHz clock that is synchronized with BCLK.

3.3V+/-0.3V single power supply

Low noise, low power consumption

Package

30pin VSOP package

Voice path block consists of TX analog inputs, output

for handset receiver, output for the hands-free

speaker, volume for the TX and RX respectively, and

the path control switches. Side tone can be added

internally and its volume is controlled through serial

CPU I/F.

- Package size; 9.7*7.6mm(pin to pin)

- Pin pitch;

0.65mm
