The SY100EP111U is a high-speed, low skew 1-to-10 differential fanout buffer designed for clock distribution in new, high-performance systems. The internal 2:1 mux allows the input to select between two differential clock sources.
The SY100EP111U is specifically designed for low skew. The interconnect scheme and metal layout are carefully optimized for minimal gate-to-gate skew within the device. Wafer characterization and process control ensure consistent distribution of propagation delay from lot to lot.
The VBB output is intended for use as a reference voltage for single-ended reception of ECL signals to that device only. When using VBB for this purpose, SY100EP111U is recommended that VBB is decoupled to VCC via a 0.01F capacitor.
