DESCRIPTION
The FPD87346 is a timing controller that combines
an LVDS single pixel input interface with TI's
Reduced Swing Differential Signaling (RSDS™)
output driver interface for (SVGA) XGA and Wide
XGA resolutions. It resides on the TFT-LCD panel
and provides the data buffering and control signal
generation for (SVGA) XGA, and Wide XGA graphic
modes. The RSDS™ path to the column driver
contributes toward lowering radiated EMI and
reducing system dynamic power consumption.
This single RSDS™ bus conveys the 8-bit color data
for (SVGA) XGA, and Wide XGA panels at 170 Mb/s
when using VESA 60 Hz standard timing.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
