The SY55854UYY is a fully differential, CML, 2x2 crosspoint switch. The non-blocking design allows any input to be connected to any output. Varying the state of the select inputs allows SY55854UYY to be used in backup, fault tolerant, protection, and backplane distribution applications.SY55854UYY inputs can be terminated with a single resistor between the true and the complement pins of a given input.The SY55854UYY is a member of Micrel's new SuperLite™ family of high-speed logic devices. This family features very small packaging, high signal integrity, and flexible supply voltage operation.
