DS90C189-Q1EVM User Guide
The DS90C189-Q1EVM (Evaluation Module) helps designers evaluate the performance of the DS90C189-
Q1 Low Power 1.8V RGB-to-Open LDI (LVDS) Bridge. The device operates from a single 1.8V supply and
can drive up to SXGA+ 1400x1050 at 60Hz (Single In / Single Out) or WUXGA+ 1920x1440 at 60 Hz
(Single In / Dual Out). The DS90C189-Q1 converts up to 24 bits (single pixel 24 bit color) of 1.8V
LVCMOS data into one or two channels of 4 data + clock (4D+C) reduced width interface LVDS
compatible data streams.
