3.2 AD9398
The chip of high-definition multimedia interface, AD9398 HDMI (High-D efinition Multimedia
Interface) this interface is the digital interface standard that bring up rapidly. The use of this
interface is the transmission of electronic video signal of standard definition and high definition, and
this interface provide the content protect technology. AD9398 also support HDCP (High bandwidth
Digital Content Protection). AD9398 include a HDMI 1.0 interface module and a HDCP module. The
inputted HDMI signal will be sent to the interface of this chip to make the decoding, simultaneity
24-bit digital RGB signal and the related sync signals are outputted to N602 PW118 to make the
processing. Moreover, HDCP module makes the communication by DDCSDA, DDCSCL and HDMI
signal sources to make the video signal decoding. The chip connect a external memory N207
24LC168SN that store the secret key of decoding required by HDCP, and make the communication
by the pin MCL, MDA of AD9893.
