... General Description The SY55854U is a fully differential, CML 2-crosspoint switch. The non-blocking design allows any input to be connected to any output. Varying the state of the select inputs allows SY55854U to be used in backup, fault tolerant, protection, and applications. SY55854U inputs can be terminated with a single resistor between the true and the complement pins of a given input ...

... CML Output (Differential). This is one output from the crosspoint. Input S0 selects either the D0 or the D1 input to be switched to this output. 2 Package Lead Finish 854U Sn-Pb 854U Sn-Pb 854U with NiPdAu Pb-Free bar-line indicator Pb-Free 854U with NiPdAu Pb-Free bar-line indicator Pb-Free hbwhelp@micrel.com SY55854U M9999-032207-E or (408) 955-1690 ...

... Also, using the CC ≤ 3.0V, connect the select inputs independently, SY55854U functions as two multiplexers. Setting the select inputs to static values turns SY55854U into a dual buffer fan-out buffer. To make larger crosspoints, cascade SY55854U devices, either in a tree Banyan structure, as appropriate for your application. (1) ...

... All inputs accept the output from any other member of this family. All outputs are source terminated 100Ω CML differential drivers as shown in Figures 3 and 4. SY55854U expects the inputs to be terminated, and that good high speed design practices be adhered to. SY55854U inputs are designed to accept a termination resistor between the true and complement inputs of a differential pair ...
