The PI90LV024 and PI90LVB024 are monolithic dual 2x2 asynchronous crosspoint/repeater switches. The crosspoint function is based on a multiplexer tree architecture. Each 2x2 switch can be considered as a pair of 2:1 multiplexers that share the same inputs. The signal path through each switch is fully differential with minimal propagation delay. The signal path is unregistered, so no clock is required for the data inputs. The signal line drivers and receivers use Low Voltage Differential Signaling (LVDS) to achieve signaling rates as high as 650 Mbps.
