AK2306 and AK2306LV are two 2-channel PCM codecs suitable for ISDN terminal adapters, supporting both European and Japanese compression algorithms.
The AK2306/AK2306LV is a 2‑channel PCM codec designed for ISDN/VoIP terminal adapters. It integrates A‑law/µ‑law compression, gain adjustment, mute, power‑down, and a built‑in ring‑tone generator, supporting PCM data rates from 128 kHz to 4.096 MHz.
The document provides a block diagram, package pin configuration, pin functions, circuit description, mechanical dimensions, and important usage notices, enabling designers to implement the codec in various telecommunication systems. This manual is written in Japanese.
