AK2510

Voice Switch LSI for Hands-Free Phone

GENERAL DISCREPTION

The AK2510 is full digital voice switch LSI for

hands-free phone. The AK2510 included PCM

interface, input level adjustment for transmit

path and receive path respectively, transmit and

receive attenuator, background-noise level

detector for each path.

Additionally, the AK2510 has a CPU serial

data interface for the voice switch function

control, PCM data mode select, A/µ-Law select,

mute, through, and selection of the transmit,

receive, idle or normal mode.

It is not necessary for the AK2510 to be add the

external components

FEATURES

■ High quality voice switched algorithm

■ Robust against Back Ground Noise Level

(max-20dBm0)

■ Applicable big Line loss (max-40dB)

■ 3.3V or 5.0V power supply

■ PCM I/F: PCM data mode (Short or Long

Frame), 16bit linear data mode, AK130

B1/B2 data mode

■ A/µ-Law selectable

■ BCLK: 512kHz, 2.048MHz

■ Serial CPU interface

■ Easy to optimize the parameter; no need to

add the external component

■ Low power consumption (Typ. 0.7mA@3.3V,

1.2mA@5.0V)

Function

PCM data rate is available for 512kHz or 2.048MHz that synchronizes

with BCLK. Several kinds of data format (Long Frame, Short Frame,

Linear, AK130 B1, AK130 B2) are available.

Interface for the internal register and it can change volume, voice

switch parameters, voice switch parameters and PCM data format.

-16～+15dB Digital volume to adjust the signal level of transmit path.

-16～+15dB Digital volume to adjust the signal level of receive path.
