*SPECIFICATIONS
Unless otherwise specified, dynamic measurements are made with all outputs terminated into 50 Ω /V
of NECL/PECL signals to 50 Ω input oscilloscopes. If preservation of DC levels is not required, then the 56003265-1, 0.1 µ f
DC block or the 56003270-2 12 dB AC-coupled attenuator may be used to connect the NECL/PECL outputs to 50 Ω input
instruments.
(2). These parameters are not supplied by the device manufacturer and are, therefore, not guaranteed.
(3). fMAX is measured by AC coupling a sine wave to the ÷2 CLK input using the differential input mode (switch up). The
÷2 and the ÷4 dividers are cascaded, and the ÷8 outputs are then measured. The fMAX measurement is then repeated by
clocking the ÷4 CLK input with the sine wave.

*All measurements are made with outputs
terminated into 50 Ω /V
550NQ4X/PQ4X, four-channel NECL/PECL
Terminator, connected to a 50 Ω input
sampling oscilloscope.
Notes:
(1). The output rise and fall times are
measured with all outputs terminated into 50 Ω
/V
be terminated into 50 Ω /V
into a 50 Ω loads. However, if only one pair of
complementary outputs is used, the other pair
may be left unterminated. If a single output is
used, one other complementary output must be
terminated; otherwise, output waveform
distortion and rise time degradation will occur.
Use the PRL-550NQ/PQ4X, four channel
NECL/PECL Terminators, respectively, for
the 50 Ω /V
