ASAHI KASEI [AK2307/LV]
2. PCM Data Interface
AK2307/LV supports 4 PCM data interface modes.
- A/u-Law PCM data mode( Long or Short frame)
This mode is for interface of 64kbps PCM data which are compressed /extended by A -law or u-law. Both Long
frame
and short frame format data are acceptable. The PCM data occupies the first time slot of the PCM data bus which
is specified by the frame sync signal. Please refer to the format diagram.
- 16 bit Linear data Mode
This mode interfaces the 16 bit linear PCM data. PCM CODEC of AK2307/LV operates at 14 bit accuracy. The 2
bits
of the LSB are fixed in the 16 bit data stream.
- AK130 B1 Mode
This mode provides the PCM data Interface to AK130, the TCM transceiver for PBX/KTS system. PCM data format
is 64kbps A-law or u-law data. The timing between data and FS is different from the A/u-Law PCM data mode
written above. In this mode the PCM data are transmitted/received via B1 channel , one of the PCM data
channel of the AK130.
- AK130 B2 Mode
This mode provides the PCM data interface to AK130 B2 channel in as same manner as AK130 B1 Mode.
In every modes, the digital voice data are in and out from DR and DX pin and the bit clock and the 8KHz frame sync
signal will be fed via BCLK and FS, respectively. The order of PCM and linear data is MSB first .

2-1. Selection of the interface mode
These four interface modes are selectable through the CPU register which specified below.
A/u-Law selection is also selectable from the same CPU register and it is effective in the u/ A-law interface mode and
AK130 B1/B2 modes.
