LVDS Interface ICs
4bit LVDS Receiver
BU90LV048
●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.
Driver and Receiver of 4 bits operate to 250MHz. It can be used for a variety of purposes, home appliances such as
LCD-TV, business machines such as decoders, instruments, and medical equipment.
No.12057EAT03

Technical Note
Drive strength select pin :
When SL is low or open, Rout set 8mA
mode.
When SL is high, Rout set 6mA mode.
Receiver enable pin: When EN is
Low or open, the receiver is disabled. When
EN is high, the receiver is enabled.
