● IC3901/3900 (TDA7480)
This is a class-D audio output amplifier. For the output stage, as in the case of the switching power supply, the
switching technology is adopted. Therefore the output stage corresponds to the switching circuit. The merit of the
class-D technology is high circuit efficiency and less power loss.
● IC2001 (IXB427WJ)
This is a main microprocessor, which communicates with the display section and operates the system.
The entire system is IC-controlled.
● IC1904 (SiI9021)
This is a digital interface receiver with the High-bandwidth Digital Content Protection (HDCP) constructed of the
Dual-Input type TMDS (Transition-Minimized Differential Signaling).
It supports both HDMI (High-Definition Multimedia Interface) and DVI (Digital Visual Interface).
