... This excellent signal PP fidelity along with low power consumption of 850 mW make the CLC018 ideal for digital video switching plus a variety of data communication and telecommunication applications. The fully differential signal path provides excellent noise im- munity, and the I/Os support ECL and PECL logic levels. In ...

... DATA INPUT PINS DI0 and DI0 through DI7 and D17 are the data input pins to the CLC018. Depending upon how the Power pins are con- nected (please refer to the Power Pin section above) the data may be either differential ECL, or differential PECL. To drive the CLC018 inputs with a single-ended signal, please refer to the section “ ...

... Differential inputs are the preferred method of providing data to the CLC018, however, there are times when the only sig- nal available is single ended. To use the CLC018 with a single ended input, the unused input pin needs to be biased at a point higher than the low logic level, and lower than the high logic level ...

... The most robust solution for single ended inputs is to place a comparator with hysteresis in front of the CLC018. Such a part is the MC10E1652. See Figure 6 for an example of how to hook this up. FIGURE 5. Single Ended Input to CLC018 FIGURE 6 ...

... EXPANDING THE NUMBER OF INPUT PORTS Expanding the number of inputs in a switch array is accom- plished by wire-ORing the outputs together, and TRI- STATEing the outputs of the CLC018s that do not have their inputs selected. The output bus should be a controlled im- pedance transmission line with proper termination. This is shown in Figure 11 ...
