Description
The PI90LV044 and PI90LVB044 are monolithic dual 2x2 asyn-
chronous 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 650Mbps.
The LVDS standard provides a minimum differential output volt-
age magnitude of 247 mV into a 100 load and receipt of 100
mV signals with up to 1V of ground potential difference between a
transmitter and receiver. The PI90LVB044 doubles the output drive
current to achieve LVDS 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 baseband
(PI90LV044) and multipoint (PI90LVB044) data transmissions
over controlled impedance media.
