4 2000 Semtech Corp. www.semtech.com EDGE HIGH-PERFORMANCE PRODUCTS Edge118 Circuit Description Chip Overview The Edge118 is a clock distribution chip designed to take one input signal (IN / IN*) and fan it out 18 times to identical outputs (OUT / OUT*). The chip is designed to minimize channel to channel skew and any timing jitter. The part’s wide fanout is extremely useful in applications where many distinct copies of a signal are required on one PC Board, and these signals must all be aligned. This signal can be distributed without creating a distribution tree using multiple devices. Inputs The input signal is differential, requiring 250 mV swings for full performance operation. The inputs are ECL compatible, but may also be operated over a common mode voltage range between VEE + 1.3V and VCC – .5V . Outputs The outputs are ECL compatible differential signals with 800 mV voltage swings centered around 1.3V below GND. Operating Frequency The Edge118 is designed to maintain full performance up to at least 1000 MHz and pass 500 ps pulses.

Application Information

A .1 µF or .01 µF capacitor (with excellent high frequency characteristics, is recommended between GND and VEE. In addition, solid GND and VEE planes are recommended to provide a low inductance path for the power supply currents. Output Terminations For optimal results, all output pairs (used or unused) should be terminated, and terminated in the same manner.
