Solomon Systech Launches MIPI Master Bridge Chip SSD2802
Pioneer in adopting MIPI display interface standards for minimal wire connections and supporting high-speed, low-power half-VGA resolution displays
(Hong Kong – 29 Sept 2006) Solomon Systech Limited, a world leader in advanced display technology and a Contributor Member in the Mobile Industry Processor Interface (MIPI) Alliance, demonstrated its new SSD2802 MIPI master bridge chip at the 3rd 2006 MIPI Quarterly Meeting held last week in Montreal, Canada. The new SSD2802 is one of the world’s first master bridge chips containing an interface compliant to MIPI specifications*. It is also the first product member of Solomon Systech’s innovative display interface solutions that would help accelerating the adoption of application-rich mobile devices.
The demonstration (Figure 1) showed the SSD2802 connected to the bus of an application processor and receiving display data from the processor. It showed the capability of the SSD2802 driving via a serial bus, enabling a TFT LCD module with a MIPI compliant receiver, and displaying video content at a QVGA resolution of 30 frames per second.
The SSD2802 provides seamless connectivity for displays in mobile devices, such as mobile phones, portable multimedia players, digital video recorders, etc. Mobile devices product companies will be able to design end products with more elegant form factors with the use of the SSD2802, which converts the commonly used MCU or RGB parallel display interface to a 4-line high-speed serial MIPI compliant interface. The SSD2802 is able to support display resolutions of up to half VGA at video speed and can support a main panel and a subpanel simultaneously. Furthermore, Solomon Systech’s SSD2802 adopts the physical layer of low-voltage differential signaling as defined by MIPI specifications*, which will be able to reduce the cost of connection cables and at the same time minimize EMI issues in continuous miniaturization of end products.
The SSD2802 is versatile enough to interface to most baseband processors, application processors, or co-processors now deployed in most mobile products. The SSD2802 is able to operate in both High-Speed (HS) and Low-Power (LP) modes for data transmission to provide optimum power consumption and will consume ultra-low power in the idle state. It contains an on-chip PLL for clock generation and is packaged in a mini 5×5 mm BGA package.
Solomon Systech will be introducing complete solutions including matching LCD drivers, which will be introduced in the coming months.
