LVDS Interface LSI
27bit LVDS Dual-out Transmitter
BU90T82
General Description
The BU90T82 transmitter operates from 10MHz to
174MHz wide clock range, and 27bits data of parallel
CMOS level inputs (R/G/B24bits and VSYNC, HSYNC,
DE) are converted to eight channels of LVDS data
stream. Data is transmitted seven times (7X) stream and
reduce cable number by 3(1/3) or less.
The BU90T82 has low swing mode to be able to expect
further low power and low EMI.
Flexible Input/Output mode support various application
interfaces.
