BU7988KVT ROHM

LVDS Interface ICs 56bit LVDS Transmitter 56:8 Serializer No.12057EAT05 BU7988KVT Description LVDS Interface IC of ROHMSerializeDeserialize 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(224MHz)(NTSC, VGA, SVGA, WXGA UXGA) 2) Support spread spectrum clock generator. 3) Clock edge selectable. 4) Support reduced swing LVDS for low EMI. 5) Power down mode. 6) Package TQFP100V Applications Flat Plane Display Precaution This chip is not designed to protect from radioactivity. www.rohm.com 2011.12 - Rev.A 1/27 2011 ROHM Co., Ltd.
