BU90T81
●General
Description
The BU90T81 transmitter operates from 20MHz to
112MHz wide clock range, and 27bits data of parallel
LVCMOS level inputs(R/G/B24bits and VSYNC,HSYNC,DE)
are converted to four channels of LVDS data stream. Data is
transmitted seven times (7X) stream and reduce cable
number by 3(1/3) or less.
The BU90T81 operates from a single 1.8V supply for low
power. And the BU90T81 has low swing mode to be able to
expect further low power and low EMI .
