ASAHI KASEI [AK2306/LV] AK2306/2306LV Dual PCM CODEC for ISDN/VoIP TERMINAL ADAPTER GENERAL DESCRIPTION AK2306 is a dual PCM CODEC-Filter most suitable for ISDN Terminal Adapter. It includes Selectable A-law/u-law function, Internal Gain Adjustment from +6dB to –18dB by 1dB step control, Selectable 16Hz/20Hz Ring Tone Generator for SLIC. All of these functions are controlled by the internal register accessed through the serial interface. PCM interface of AK2306 accepts Long Frame, Short Frame clock formats and GCI format. 64 x N kHz(128k-4096kHz) clock input is available for PCM interface. AK2306 and AK2306LV are pin-compatible, but different products which power supply voltage are 5.0V and 3.3V,respectively.
