The PI90LV3811 and PI90LVB3811 consist of ten differential line drivers that implement the electrical characteristics of low-voltage differential signaling (LVDS). This signaling technique lowers output voltage levels to reduce the power, increase switching speeds, and allow operation with a 3V supply rail. Any current-mode LVDS driver will deliver a minimum differential output voltage magnitude of 247mV into a 100-Ohm load (PI90LV3811) or 50-Ohm load (PI90LVB3811) when enabled. The PI90LVB3811 doubles the output drive current to achieve LVDS levels with a 50-Ohm load. The intended application of this device and signaling technique is for point-to-point baseband (single termination) and multipoint (double termination) data transmission over a controlled impedance media of approximately 100-Ohms. The transmission media may be printed-circuit board traces, backplanes, or cables. The large number of drivers integrated into the same substrate, along with the low pulse skew of balanced signaling, allows extremely precise timing alignment of clock and data for synchronous parallel data transfers. When used with its companion 10-channel receivers, the PI90LV3810 or PI90LVR3810, over 300 million data transfers per second in singleedge clocked systems are possible with very little power. |
