PI3LVD512 3.3V, 5-differential Channel LVDS Switch Targeted for 24bit Displays Features Description • • • • • • Pericom’s PI3LVD512 is a 5-differential channel LVDS mux/ demux used to switch between multiple LVDS sources or end points. In a notebook application where analog video signals are found in both the notebook and the dock, a switch solution is required to switch between the two video port locations. With the high bandwidth of 870MHz, the signal integrity will remain strong even through the long FR4 trace between the notebook and the docking station. 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. Designed specifically to switch LVDS signals VDD = 3.3V +/-10% ESD tolerance on video I/O pins is up to 12kV HBM -3dB BW of 870MHz (typ) Low Xtalk, (-28dB typ) Low and Flat ON-STATE resistance (Ron = 3ohm, Ron(Flat) = 0.5ohm, typ) • Low input/output capacitance (Con = 6pF, typ) • Packaging (Pb-free and Green): − 56 contact TQFN (ZFE) − 42 contact TQFN (ZHE) Applications • Routes physical layer signals for high bandwidth 0B1 A1 1B1 0B2 GND A0 A1 1B2 2B1 A2 3B1 A3 A4 A5 2B2 VDD NC 3B2 GND 4B1 A2 A3 5B1 GND VDD 4B2 A4 A5 5B2 A6 6B1 GND A7 7B1 A6 A7 6B2 GND 7B2 A8 8B1 A9 9B1 SEL VDD A8 A9 8B2 NC A0 GND NC NC VDD GND Pin Description (56ZFE, top view) VDD GND Block Diagram 56 55 54 53 52 51 50 49 1 48 2 47 3 46 4 45 5 44 43 6 7 42 8 41 40 9 39 10 38 11 37 12 36 13 35 14 34 15 33 16 32 17 18 31 19 30 20 29 21 22 23 24 25 26 27 28 0B1 1B1 0B2 1B2 GND 2B1 3B1 2B2 3B2 GND VDD 4B1 5B1 4B2 5B2 GND 6B1 7B1 6B2 7B2 SEL 10-0185 1 GND 8B2 9B2 VDD GND GND 8B1 9B1 9B2 PS8979B 09/16/10 PI3LVD512 3.3V, 5-differential channel LVDS switch targeted for 24bit displays A4 A5 A6 A7 SEL VDD A8 A9 8B1 NC NC VDD 0B1 40 39 18 19 20 21 9B2 VDD 41 8B2 A2 A3 42 NC VDD 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 9b1 VDD A0 A1 NC Pin Description (42ZHE, top view) 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 1B1 0B2 1B2 2B1 3B1 2B2 3B2 VDD 4B1 5B1 4B2 5B2 6B1 7B1 6B2 7B2 VDD Note: NC pin (5) could be left floating or tied to GND 10-0185 2 PS8979B 09/16/10 PI3LVD512 3.3V, 5-differential channel LVDS switch targeted for 24bit displays Maximum Ratings (Above which useful life may be impaired.

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 bus 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. 10-0185 4 PS8979B 09/16/10 PI3LVD512 3.3V, 5-differential channel LVDS switch targeted for 24bit displays Test Circuit for Electrical Characteristics(1) 6.0V VDD 200-ohm VIN Pulse Generator VOUT D.U.T 10pF CL RT 200-ohm Notes: 1.
