The SN55LVCP22 (LVDS output) is a high-speed 2x2 crosspoint switch. The four different functions that this crosspoint provides are shown below. The functions are selected via pins SEL0 and SEL1. Control pins EN0 and EN1 enable or disable the outputs. The receiver has a wide input common-mode voltage range with an ability to accept LVDS, LVPECL and CML signaling rates (see Figure 1). The signal paths on this EVM include 8 edge-launch SMA connectors (J8-J16) for high-speed data transmission, 2 jumpers for active switch logic control, 2 jumpers (J6 and J7) for enabling and disabling the outputs, and three banana jacks (J3, J4, J5) for power and ground connections. Note GND is tied to VCC01 to allow for proper common mode termination to 50 Ω loads.

Note: This EVM contains Pb, a necessary component for QML parts
