Rohm Co. Ltd, a Kyoto-based semiconductor manufacturer of MSDL2, an LCD serial interface technology for multi-function mobile phones that builds on the previous MSDL technology to deliver transmission speeds of up to 200MBps, has completed development of MSDL3, which promises speeds of up to 450MBps.

MSDL (Mobile Shrink Data Link) is the company's proprietary high-speed differential serial transmission technology designed for high-speed, low-EMI, low-power-consumption data transmission by mobile phones.

According to the press release, the MSDL3 delivers speeds of up to 450MBps per channel and is compatible with SVGA-class LCDs (800 W 600 pixels) using six differential wires. This ensures compatibility with ultra-high resolution displays for third generation mobile phones, added the company.

In addition, Rohm has switched to a Sub-LVDS system in order to accommodate the high data transmission speeds of MSDL3. MSDL2 or MSDL3 can be used, depending on the application. MSDL2 is suitable for resolutions up to HVGA-class with low-power consumption, while MSDL3 is designed for interfaces compatible with higher resolutions.

The BU7960GU features multiple interfaces, including 24-bit RGB, Hsync, Vsync, DE and PCLK, as well as various serial interfaces, such as CLK +/-, DATA1 +/- and DATA2 +/-. A power-saving mode using clock detection is also included, said Rohm, and one of two channels can be chosen to match the data rate.

Samples of the BU7960GU MSDL3 transceiver are scheduled to ship in two months (October 2005).
