The fully non-blocking switch core is programmed through a multi-mode port interface that allows random access programming of each input/output port. Each data output can be programmed to connect to one of the 144 inputs. The signal path is unregistered and fully asynchronous, so there are no restrictions on the phase, frequency, or signal pattern on any input. Each highspeed output is a fully differential switched current driver with on-die terminations for maximum signal integrity. A multi-mode, programming interface is provided that allows commands to be sent as serial data or multiplexed parallel data. Unused channels may be powered down to allow efficient use of the switch in applications that require only a subset of the channels. A secondary serial access port allows asynchronous readba...
