BU7985KVT
BU7985KVT is 56bit LVDS Receiver 8:56 DeSerializer manufactured by ROHM.
Description
LVDS Interface IC of ROHM "Serializer" "Deserializer" operate from 8MHz to 150MHz wide clock range, and number of bits range is from 35 to 70. Data is transmitted seven times (7X) stream and reduce cable number by 3(1/3) or less. The ROHM's LVDS has low swing mode to be able to expect further low EMI.
- Features
1) Wide dot clock range: Single (112MHz)/Dual (180MHz) (NTSC, VGA, SVGA, WXGA UXGA) 2) Support clock frequency from 20MHz up to 112MHz. 3) User programmable LVCMOS data output triggering timing by using either rising or falling edge of clock. 4) User programmable LVCMOS data and clock output driving ability. 5) Support Fail-Safe Hi-z Operation. 6) 56bit LVDS transmitter is remended to use BU7988KVT.
- Applications Flat Panel Display
- Precaution
- This chip is not designed to protect from radioactivity.
