LVDS Interface ICs 4bit LVDS Transceiver BU90LV049A No.09057EAT01 ●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 1) >500 Mbps (250 MHz) switching rates 2) Flow-through pinout simplifies PCB layout. 3) 400 ps typical driver channel-to-channel skew 4) 150 ps typical receiver channel-to-channel skew 5) 3.3V single power supply design 6) ±200mV and ±350mV selectable differential signaling (driver) 7) 6mA and 8mA selectable output drive strength (receiver) 8) 3-STATE output control 9) Internal fail-safe biasing of receiver inputs 10) High impedance on LVDS outputs on power down 11) Conforms to TIA/EIA-644-A LVDS Standard 12) Industrial operating temperature 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. www.rohm.com © 2009 ROHM Co., Ltd.
