*SPECIFICATIONS
PRL-422NECL and PRL-422NECL are equivalent modules.
*Since the high frequency signals to and from the 124Ω I/O ports can not be easily measured, the 124Ω I/O ports of these adapters are first cascaded using shielded twisted pair cables, Trompeter P/N PCGOW10PCG-36
or equivalent. Input signals are applied to the 50Ω inputs of the PRL-422NECL, and outputs of the PRL-422RS are terminated into 50Ω/-2V, using the PRL-550NQ5X, four-channel NECL Terminators, connected to a 50
Ω input sampling oscilloscope.
Notes:
(1). The 50Ω output rise and fall times were measured with both the Q and
waveform degradation will occur.
