Appendix A: Options and Accessories

Output Circuit and Output Waveform. The ECL buffer (10E116) output is connected directly to the output connector. When used, these signals must be terminated to ±2 V with a 50 W resistor at the receiving side (user side). If this termination resistor is missing, the signals do not appear at the output connector. The same is true for the clock output (see Figure A-4).

The data output signal skew is held to 1 ns max. The rise and fall time depend on the buffer ICs, but neither is greater than 1 ns (see Figure A-5). Neither of these specifications includes cables; it is specified at the output connector.
