DS90C2501
Transmitter with built-in scaler for L VDS Display
Interface (LDI)
General DescriptionThe DS90C2501isa highly integrated scalingIC with LVDS
transmitter witha scaled resolutionupto SXGA+for single
pixel input. The DS90C2501isa video controller hub de-
signedtobe compatible with Graphic Memory Controller
Hub (GMCH). The input interface canbe singleor dual DVO
port (12pin per port). The high quality cubic zoom engine
scales the input graphics into the desired/optimal output
resolutionupto 1400x1050 resolution. Advanced video digi-
tal signal processing provides gamma correction, and dith-
eringfor the display output.A two-wire serial interfaceis
usedto communicate with the host system. The dual high
speed LVDS channels supports single pixel in-single pixel
out, single pixel in-dual pixel out, and dual pixel in-dual pixel
out transmission modes. The DS90C2501 compliesto Open
LDI standard, and canbe pairedup with DS90CF388re-
ceiveror FPD8531x/FPD8731x series integrated timing con-
trolleror FPDLink LVDS receivers suchas DS90CF364/
DS90CF384A/DS90CF384/DS90CF384A. The LVDS output similarto DS90C387 and DS90C387R. Thus, this trans-
mitter can be paired up with DS90CF388, receiverof
112MHz LDI chipsetor FPD-Link Receiversin non-DC Bal-
ance mode operation which provides GUI/LCD panel/mother
board vendorsa wide choiceof inter-operation with LVDS
based TFT panels.
This chipisan ideal solutionto solve EMI and cable size
problemsfor high-resolution flat panel applications.It pro-
videsa reliable industry standard interface basedon LVDS
technology that delivers the bandwidth neededfor high-
resolution panels while maximizingbit times, and keeping
clock rates lowto reduce EMI and shielding requirements.

tion” sectionof this datasheet.
