1 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. Features >500 Mbps (250 MHz) switching rates Flow-through pinout simplifies PCB layout 150 ps channel-to-channel skew (typical) 100 ps differential skew (typical) 3.7 ns maximum propagation delay 3.3V power supply design 6mA and 8mA selectable output drive strength Accepts small swing (200 mv typical) differential signal levels Supports open, short and terminated input fail-safe Conforms to ANSI/TIA/EIA-644 Standard Industrial temperature operating range (-40 to +85 ) Applications Car Navigation System Copier Digital TV (Signal System) FA equipment Medical equipment Vending machine, Ticket vending machine Precaution This chip is not designed to protect from radioactivity. This document may be used as strategic technical data which subjects to COCOM regulations.
