A PLD (Programable Logic device) is equipped on KX-NS5173/74, and this device has several interfacing functions as below.

Silicon Labs Si32261 CODEC is installed. The analogue features such as BN, frequency characteristic, volume level, sidetone
are configured by PLD CODEC interface DCLK, CS, DOUT, DIN. Also, it converts A/D to D/A, and 4-line-analogue signal to
PCM code in G.711 format.
