KX-HDV330 Series
4.2.8.
ASIC
IC101 and IC503(ASIC) are connected by an I2C communication.
EHS terminals are controlled by IC503 (ASIC).
EHS terminals are controlled by IC503 (ASIC).
*This ASIC supports Plantronics and Jabra EHS.
Plantronics control signals : PSB IN/OUT
Jabra control signals : JABRA_UTX/URX
Jabra control signals : JABRA_UTX/URX
The audio signals are exchanged with IC101 through HEADSET JACK.
4.2.9.
BT(Bluetooth) Module
The BT Module (IC105) is controlled by IC101 using serial communication command (IC105 pin6,9).
This BT Module supports Plantronics and Jabra BT headset (narrow&wide band), voice signals can be transmitted/received
through PCM (IC105 pin2,3,31,32)
