DESCRIPTION
The FPD87208AXA is a timing controller that
combines an LVDS single pixel input interface with TI
Reduced Swing Differential Signaling (RSDS™)
output driver interface for XGA and Wide XGA
resolutions. It resides on the TFT-LCD panel and
provides the data buffering and control signal
generation for 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 6-bit color data for
XGA, and three different WXGA resolutions.

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.
