The PI90LVR3810 has integrated edge-triggered D-type flops. Any of the differential receivers will provide a valid logical output state with a ±100mV differential input voltage within the input common-mode voltage range that allows 0 to 3V of ground potential difference between two LVDS nodes. The independent EN pins can be used to place the outputs in either a normal logic state (high or low logic levels) or a high-impedance state. In highimpedance state, outputs neither load nor drive the bus lines. The intended application of these devices, and their signaling techniques, is for point-to-point baseband data transmission over controlled impedance media of approximately 100-Ohms with a 100Ohm termination resistor. The transmission media may be printed circuit board traces, backplanes, or cables. The PI90LV3810’s 10 receivers integrated into the same substrate allow precise timing alignment. In addition, the PI90LVR3810's integrated registers resynchronize the data to the system clock, for additional signal deskew. The integrated registers in the PI90LVR3810 are particularly suitable for interfacing with LVDS drivers such as the PI90LV3811 over long distances where signal-to-signal skew may be a problem. On the positive transition of the differential clock (CLK±) input, the Q outputs of the flip-flop take on the logic levels set up at the differential data (RIN±) inputs. PI90LV3810 Old data can be retained or new data can be entered while the outputs are in the high-impedance state. The EN pins do not affect the internal operation of the flip-flops.
