• Manufacturer Part Number: MB86292
• Description: Graphics Display Controller
• Manufacturer: Fujitsu Media Devices Limited

Note : The video capture interface inputs digital video signals in the ITU-RBT-656 format.
Notes : The graphics memory interface connects the MB86292 to the external memory used for graphical image
*1 : Do not connect anything.
*2 : Input the "H" level.
Notes : The clock input block inputs the clock signal that serves as the basis for the reference clock for the internal

operating clock and display dot clock. Usually input 4 Fsc ( 14.31818 MHz for NTSC). The internal PLL
generates the internal operating clock signal of 100 MHz and the display reference clock signal of 200 MHz.
generated by the internal PLL and the bus clock BCLKI input to the host CPU interface. Select the BCLKI
input to use the host CPU bus at 100 MHz.
Memory bus data can be selected between 64 bits and 32 bits. To use 32-bit data, leave the MD32-MD63
The internal operating clock signal to be used can be selected between the clock signal (100 MHz)
data. The interface can directly accept 128-Mbit SDRAM or 64-Mbit SDRAM (with a 16-bit or 32-bit
data bus) without any external circuit.

Connect the MCLKI pin to the MCLKO pin.
When RGBEN is fixed to 1, MD55-MD63 can be used as graphics memory bus data. When RGBEN is
fixed to 0, RGB0-2 is output.
