Overview

ASAHI KASEI [AK2303LV] AK2303LV Dual PCM CODEC for PBX Analog Line Card GENERAL DESCRIPTION AK2303LV is a 3.
3V dual PCM CODEC-Filter most suitable for analog line card of PBX switch.
CODEC-Filter is compliant with G711/G712 recommendations.
It includes Selectable A-law/u-law function, Internal Gain Adjustment from +6dB to –18dB by 1dB step control.
All of these functions are controlled by the internal register accessed through the serial interface.
Additionally, channel mute and A-law/u-law selection is controlled by the hard pin.
PCM interface of AK2303LV supports Long Frame, Short Frame clock formats and GCI format.
4.
096MHz, 2.
048MHz bit clock input is available for PCM interface.
