4. Circuit Description
1.RTD 2553V
Realtek RTD2553V series products are all-in-one LCD monitor controllers supporting UXGA / WSXGA+ / WXGA+ / SXGA
(optional), and integrate Realtek high performance ADC, TMDS Rx(optional),scaling engine, OSD engine, LVDS Tx, RSDS
Tx and so on. Moreover, all products are pin compatible in QFP128-pin package to save cost and make the design easier.
2. RTD2120
This chip is the micro-processor of LCD monitor. It uses the design ware DW8051 of Synopsys as the 8051 core of this chip
and is compatible with other industry 8051 series. Also, 96Kbyte FLASH with 8 bit bus is embedded in this chip which is
licensed from TSMC 0.18um e-FLASH process. Here we use the package of PLCC44/LQFP48 if we would like to have a
discrete MCU controller or we make a multi-chip package with our LCD monitor controller to form one chip package to save
the cost of package and PCB material.
