DESCRIPTION
The QS3B491 and QS3B2491 are high speed Crossbar switches
organized as four independent 9-bit wide ports using QSI’s 0.5micron
CMOS technology. The switch matrix consists of N-channel FET switches
controlled by the configuration logic. When closed, the switches permit
bidirectional data flow with near-zero propagation delay. The N-channel
FETs also facilitate 5V to 3.3V, and 5V to 2.5V voltage translation between
ports.
The switch matrix can be configured for independent connection be-
tween any two ports as well as for multi-port broadcasting. Configuration
control is either synchronous or asynchronous. In the synchronous mode,
the control logic behaves like a Register. New configuration is stored on the
positive edge of the Clock (CLK) if Clock Enable (
CLKEN) is at logic LOW.
