... LVDS Interface ICs 70bit LVDS Distributor BU90RT102 ●Description LVDS Interface IC of ROHM "Serializer" "Deserializer" operates 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. ...
