With new notebook architecture allowing users the ability to upgrade their graphics power, notebook designers need an effective way to switch between the upgraded graphics path. Pericom's LVDS switch allows users to switch between two graphics processors in a single notebook, driving the internal panel. PI3VLVD1012 can support 18bit or 24bit panels. With the high bandwidth of ~1.2GHz, the signal integrity will remain strong even through the long FR4 trace through the notebook. In addition to high signal performance, the video signals are also protected against high ESD with integrated diodes to VDD and GND that will support up to 12kV of ESD HBM protection.

For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Guaranteed by design. 3. The switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25ns for 10pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the LVDS switch when used in a system is determined by the driving circuit on the driving side of the switch and its interactions with the load on the driven side. 08-0246 5 PS8927C 09/26/08 PI3LVD1012 3.3V, 10-differential channel Dual-LVDS switch targeted for 24bit displays Test Circuit for Electrical Characteristics(1) 6.0V VDD 200-ohm VOUT VIN Pulse Generator D.U.T 10pF CL RT 200-ohm Notes: 1.
