| PI2LVD512 1.8V, Wide-Bandwidth, 5 Differential Channels, 2:1 Mux/DeMux Switch with Dual Enable Features * * * * * * * * 5 different channels, 2:1 Mux/DeMux LVDS signal switching beyond 2.5Gbps Low bit-to-bit skew, 8ps Low crosstalk: -70dB @ 10MHz Switching speed: 4ns VCC Operating Range: +1.5V to +2.0V ESD: Data bits @ 8kV HBM, select bits @ 2kV HBM Packaging (Pb-free & Green): - 64-pin TSSOP (A) Description Pericom Semiconductor's PI2LVD512 is a 10- to 5-channel multiplexer/demultiplexer Switch. The device multiplexes differential signals to one of two corresponding outputs. The switch is bidirectional. It is designed for low bit-to-bit skew, high channel-to-channel noise isolation and is compatible with various differential standards such as LVDS Pin Description 64-TSSOP Applications * Routes physical layer signals for high-speed, high bandwidth differential protocols Block Diagram 1 PS8807 01/18/06 PI2LVD512 1.8V, Wide-Bandwidth, 5 Differential Channels, 2:1, Mux/DeMux Switch with Dual Enable Maximum Ratings (Above which useful life may be impaired.
