DISPLAY SUBSYSTEM
The 965GM contains a dual-channel 24-bit LVDS interface. Notice that for designs implementing only a single
LVDS channel, the LOWER channel of the interface should be used.
• Integrated dual 24-bit LVDS interface.
• 595 Mbps/channel with 85 MHz pixel clock rate.
• FPDI-2 compliant; compatible with receivers from National Semiconductor, Texas Instruments, and THine.
• OpenLDI compliant excluding DC balancing.
• Programmable internal spread spectrum controller for the LVDS signals.
• LVDS eye pattern to improve testability of LVDS module
LCD Power On Sequence
LCD timing must follow up below specification to meet the minimum requirements.
• ENAVDD(LCDVCC)´ SHFCLK(DATA)--´BLON (power on sequence)
• BLON´SHFCLK(DATA)--´ENAVDD(LCDVCC) (power off sequence)
Note A: This timing depends on LCD specification
