27bit LVDS Trabsmitter 27:4 Serializer - BU90T81

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 (7×) stream and reduce cablenumber by 3 (1 / 3) or less. The ROHM's LVDS has low swing mode to be able to expect further low EMI.Driver and Receiver of 4 bits operate to 250MHz. It can be used for a variety of purposes, home appliancessuch as LCD-TV, business machines such as decoders, instruments, and medical equipment.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
