Simple, Low Power and Low Cost Timing Controller for LCD Monitor
(Hong Kong – 30 June 2006) Solomon Systech Limited is proud to launch their TFT LCD timing controller, SSD2900, which supports high resolution – SXGA (1280 x 1024) and UXGA (1600 x 1200) TFT-LCD monitors. This simple but specific IC specializes in its integrated dual LVDS (Low-Voltage Differential Signaling) receivers and RSDS (Reduced Swing Differential Signaling) transmitter.
SSD2900 supports 18/24 bit-per-pixel LVDS input and transmits 18/24 bit-per-pixel RSDS data. The LVDS and RSDS are low voltage swing interfaces for low EMI solution. SSD2900 has on-chip spread spectrum controller which provides total solution to EMI. It reduces EMI by tolerating spread spectrum interface at LVDS input, whereas the spread spectrum controller at RSDS output varies the clock to wider the spectrum in frequency domain with center spread +/- 0.25% of nominal frequency at 2kHz. In addition, the embedded timing controller operates in DE-only mode which provides accurate timing control signals for source/gate drivers. Bandwidth of one channel LVDS is 25-85MHz, whereas maximum output RSDS bandwidth is 85MHz. Moreover, SSD2900 supports virtual 8-bit color depth in FRC mode. Its low power core operates from 3.0V to 3.6V. The usage of SSD2900 is simply hardware, no application software and command required.
