Tel: 408-943-2600 wwwhttp://www.cypress.com Product Description The SC680 is a high fanout system clock buffer. Its primary application is to create the large quantity of clocks needed to support a wide range of applications that requires those clock loads signal that are referenced to a single existing clock. Loads of up to 30 pF are supported. One of the chief applications of this component is where long traces are used to transport clocks from their generating devices to their loads. The creation of EMI and the degradation of waveform rise and fall times is greatly reduced by running a single reference clock trace to this device and then using it to regenerate the clock that drives shorter traces. Using these devices EMI is therefore minimized and board real estate is saved.

For proper operation, Vin and Vout should be constrained to the range: VSS<(Vin or Vout)<VDD Unused inputs must always be tied to an appropriate logic voltage level (either VSS or VDD).
