•
SDI Equ 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)
