LVDS Interface ICs

4bit LVDS Receiver

BU90LV048

No.12057EAT03

●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) 150 ps channel-to-channel skew (typical)

4) 100 ps differential skew (typical)

5) 3.7 ns maximum propagation delay

6) 3.3V power supply design

7) 6mA and 8mA selectable output drive strength

8) Accepts small swing (200 mV typical) differential signal levels

9) Supports open, short and terminated input fail-safe

10) Conforms to ANSI/TIA/EIA-644 Standard

11) 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
