*All dynamic NECL measurements are made with outputs terminated into 50 Ω/-2 V, using the PRL-550NQ4X, four channel NECL Terminators, connected to a
50 Ω input sampling oscilloscope. TTL inputs are terminated with 50 Ω.
Notes:
(1) The rise and fall times of the NECL outputs are measured with all outputs terminated into 50 Ω/-2 V. An unused complementary output must be either terminated into 50 Ω/-2 V
or AC coupled into a 50 Ω load; otherwise, output waveform distortion and rise time degradation will occur. Use the
PRL-550ND4X or PRL-550NQ4X, two or four channel NECL Terminator, for the 50 Ω/VTT termination and for connection to 50 Ω input oscilloscopes, when DC coupling is necessary. Otherwise, use the
PRL-ACT-50, dual AC coupled 50 Ω-termination for terminating unused outputs and the
PRL-SC-104, 0.1 µf DC block, for AC coupling into a 50 Ω load or scope. The
PRL-ACX-12dB, AC coupled 12 dB attenuator, can also be used either for termination or for connection to an oscilloscope.
(2) In Normal mode, the pulse width of the f/n outputs is equal to the period of the VCO frequency, varying from 714 ps to 1.42 ns as the VCO frequency is changed from 1.4 GHz to 700 MHz. In Square Wave mode (Bit 9 up), the pulse width is
1/2 the f/n clock period. For optimum performance, use the square wave output mode for TTL
outputs. Beyond 300 MHz, reduced swings of the TTL outputs no longer comply with the standard Hi and Lo levels of 2 V and 0.8 V, respectively.
