Description

The PI90LV024 and PI90LVB024 are monolithic dual 2x2 asynchronouscrosspoint/repeater switches. The crosspoint function isbased on a multiplexer tree architecture. Each 2x2 switch can beconsidered as a pair of 2:1 multiplexers that share the same inputs.

The signal path of  through PI90LV024 and PI90LVB024 each switch is fully differential with minimalpropagation delay. The signal path is unregistered, so no clock isrequired for the data inputs. The signal line drivers and receivers useLow Voltage Differential Signaling (LVDS) to achieve signalingrates as high as 650 Mbps.

The LVDS standard provides a minimum differential output voltagemagnitude of 247mV into a 100 Ohm load and receipt of 100mVsignals with up to 1V of ground potential difference between atransmitter and receiver. The PI90LVB024 doubles the output drivecurrent to achieve Bus LVDS signaling levels with a 50 Ohm load.

The intended application of PI90LV024 and PI90LVB024 is for loop-through andredundant channel switching for both point-to-point base-band(PI90LV024) and multipoint (PI90LVB024) data transmissions overcontrolled impedance media. The package pin assignments enableseasy routing for applications requiring signal feedback.
