The devices are designed to support data rates in excess of 400 Mbps (200 MHz) using Low Voltage Differential Signaling (LVDS) technology. The PI90LV047A/PI90LVB047A accept low-voltage TTL/CMOS input levels and translates them to low-voltage (350 m V) differential output signals. The PI90LVB047A doubles the output drive current to achieve Bus LVDS signaling levels with a 50-ohm load. A doubly terminated Bus LVDS line enables multipoint configurations. In addition, the driver supports a 3-state function that may be used to disable the output stage, disabling the load current, and thus dropping the device to an ultra low idle power state of 13m W typical. The devices have a flowthrough pinout for easy PCB layout. The EN and EN inputs are banded together and control the 3-state outputs. The enables are mon to all four drivers. The intended application of these devices and signaling technique is for both point-to-point baseband (PI90LV047A) and multipoint (PI90LVB047A) data transmission over controlled impedance media.
