CIRCUIT DESCRIPTION
Description of Operation of the DVI-OUT Board Circuit
This board receives a video signal input from a projector's DVI Port and an output video signal of MM2000
(option), and transmits either video signal to DVI I/F of TI circuit at the following stage.
1. Video input
1.1 DVI system
[Single Link/8Bit x 2Port]
- Video signals (DVI/IF) from the external input ports DVI-A (M6501) and DVI-B (M6500) are each input
to IC6503 and IC6502 (both are Sil1161) with TMDS.
- In Sil1161s input TMDS signals are parallel-converted to R,G,B (16 bits each, 48 bits total) and output
to IC6504 (EP2C35F672), together with the clock and sync signals.
[Twin Link/10Bit by 2Port]
- In compliance with high resolution,etc. Twin Link is supported in which input insufficency at 1Port is
compensated for at 2Port side.
- The basic operation is the same as that of Single Link. A-Port (IC6503-IC6506 line) performs 8Bit
processing, while B-Port (IC6502-IC6505 line) performs 2Bit processing.
- Data reconstruction is made by the TI circuit at the following stage.
1-2. MM2000 system
- Video signals are input with LVDS I/F in such a manner that the EVEN data are via PONA to IC6500
while the ODD data via PONB to IC6501. THC63LVD104S is employed for both IC6500 and IC6501.
- In THC63LVD104S input LVDS signals are parallel-converted to R,G,B (10 bits each, 30 bits total)
and output to IC6504 (EP2C35F672), together with the clock and sync signals.
2. Data Processing and Selector
- IC6504 (EP2C35F672) performs input switching so as to output the video input signal from either the
external DVI port or MM2000. Switching control is made from the CPU PWB. In this case connector POTY#1
is to be switched according to the logic below:
H:DVI
L:MM2000
- Each input signal, together with the clock and sync signals, is output with R,G,B (16 bits each, 48 bits total)
to IC6506 and IC6505 (both are Sil1160).
- The output formats for each input signal are as follows:
- DVI
Single Link
Port-A: 8 bit data via IC6503 is output to IC6506 as 8 bits.
Port-B: 8 bit data via IC6502 is output to IC6505 as 8 bits.
Dual Link
Port-A: 8 bit data via IC6503 is output to IC6506 as 8 bits.
Port-B: 2 bit data via IC6502 is output to IC6505 as 2 bits.
- MM2000
Port-A: 8 bit data via IC6503 is output to IC6506 as 8 bits.
Port-B: 2 bit data via IC6502 is output to IC6505 as 2 bits.
