*All dynamic NECL measurements are made with outputs terminated into 50 Ω/ VTT, using the PRL-550NQ4X, four channel NECL Terminator, connected to a 50 Ω input sampling oscilloscope. TTL outputs are terminated to 50 Ω.
Notes:
(1). The output rise and fall times of each NECL channel are measured with its complementary output terminated into 50 Ω/ VTT. An unused complementary 50 Ω output must be either terminated into 50 Ω/ VTT or AC coupled into a 50 Ω load; otherwise, output waveform distortion and rise time degradation will occur. Use the PRL-ACT-50, Dual Ch. AC-Coupled 50 Ω Termination, for the 50 Ω/ VTT termination. Use the PRL-SC-104 or PRL-ACX-12dB (0.1 µf DC block and 12 dB AC-coupled attenuator, respectively) for connection of NECL signals to 50 Ω input oscilloscopes.
