The major difference between BLVDS and LVDS is that Bus LVDS drivers use a higher (10mA) current drive output circuit. The higher drive allows BLVDS devices to drive heavily loaded fully populated multipoint backplanes. In addition to the higher drive, BLVDS devices have slower output edge rates to reduce reflections caused by stubs in multipoint backplane applications. Both technologies have 100mV input sensitivity, fully differential signal swings, and high levels of ESD immunity. National Semiconductor LVDS and BLVDS devices allow for easy hot-insertion and high impedance power down in high reliability applications.
