•SDI Equalizer + Deserializer sends out YUV(4:2:2) 20bit digital Signal fed SD/HD-SDI. 20bit Signal as
in output sends out audio Signal.
•HDMI S/W, ADC(HDMI+ADC -Input) sends out 8bit 2ch R,G,B data selected DVI or HDMI signal.
YPbPr(480p,720p,1080i-Input) sends out 30bit 2ch R,G,B data via A/D CONVERTER.
•Analog R,G,B(IBM,VESA -Input) is sent out 30bit 2ch R,G,B data via A/D CONVERTER.
•ALTERA FPGA A makes DIGITAL Signal switching then send out ALTERA FPGA B.
In Fast Mode, it sends out ALTERA FPGA B by deinterlacing without using Scaler.
It sends out I2S Signal in H part by extracting Audio signal on SD/HD-SDI..
•3D-ROM handles with CVBS1~3.
•HDMI, DVI, RGB, and YPbPr don’t get a signal at the same time.
•After changing Digital signal into Analog one, Audio AMP(LM4849) amplifies audio then puts out
Audio Out(J16).
•SAMSUNG K4S641632H-UC75 memory is used for 3D-COM.
•Serial Flash Memory is a device that saves images and loads them when they are needed.
•CPU controls whole circuit.
•Temperature sensor and keys are under CPU control.
•Scaler/Deinterlace have 4 of DDR, save images, and load them whenever needed.
•PCF8574 ‘s role is to extend I/O port.
•GPI Remote(J23) consis of parallel switch then control monitors the outside.
•GPI IN/OUT(J21, J22) controls protocol monitors or supports TSL protocol.
•EXT. SYNC Generater takes out SYNC on Analog signal, makes CLK,H,V F, and puts out FPGA.
•Ethernet Module is for Program Download and Calibration by connecting an Ethernet Cable with
I2C signal.
•[Ethernet & USB]
- Updates new firmware such as features, debugging.
•~ AC IN
- AC 100 ~ 240V (1.6A/50~60㎐)
- DC 12V(MAX 3.5A)
