Description
The PI90LV024 and PI90LVB024 are monolithic dual 2x2 asynch-
ronous 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.
The LVDS standard provides a minimum differential output voltage
magnitude of 247mV into a 100 Ohm load and receipt of 100mV
signals with up to 1V of ground potential difference between a
transmitter and receiver. The PI90LVB024 doubles the output drive
current to achieve Bus LVDS signaling levels with a 50 Ohm load.
The intended application of these devices is for loop-through and
redundant channel switching for both point-to-point base-band
(PI90LV024) and multipoint (PI90LVB024) data transmissions over
controlled impedance media. The package pin assignments enables
easy routing for applications requiring signal feedback.
