Description

The PRL-435N is a high-speed Differential Input AND Gate module intended for applications in the GHz frequency range. It can be used for clock or trigger gating, or for generating narrow pulses by applying two differential signals with small different delays to its inputs. As an example, a pulse as narrow as 600ps can be generated when the PRL-435N is driven by two unequal pairs of cables.

The PRL-435N model has NECL inputs and outputs. Using AC coupling, the PRL-435N can also receive GHz sinewave or PECL signals.

Complementary outputs of the PRL-435N, with internal pull down resistors, can drive either 50 Ω loads terminated into V_TT, or AC-coupled 50 Ω loads.

The PRL-435N is housed in a 1.3 x 2.9 x 2.2-in. extruded aluminum enclosure and is supplied with a ±8.5 V/1.8 A AC/DC adapter.

Notes:

All dynamic measurements are made with outputs terminated into 50 Ω/V_TT, using the PRL-550 Series, four channel ECL/PECL/LVPECL Terminators, connected to a 50 Ω input sampling oscilloscope.

The output rise and fall times are measured with with all inputs terminated into 50 Ω/V_TT. For best performance all outputs should be terminated into 50 Ω/V_TT or else AC- coupled into 50 Ω loads. If a single output is used, its complement must be terminated; otherwise output waveform distortion will occur. If one pair of complementary outputs is used, the other complementary pair may remain unterminated. Use the PRL-550 Series, four channel ECL/PECL/LVPECL Terminators, for the 50 Ω/V_TT termination and for connection of ECL/PECL/LVPECL signals to 50 Ω input oscilloscopes. The PRL-ACT-50, Dual Channel AC-Coupled 50 Ω Terminator, may also be used to provide the 50 Ω/V_TT termination. If preservation of DC levels is not required, then the PRL-SC-104, 0.1 µf DC block or the PRL-ACX-12dB, 12 dB AC-coupled attenuator, may be used to connect the NECL/PECL/LVPECL outputs to 50 Ω input instruments.

f_MAX is measured using differential inputs only. The outputs are first divided by four, using the PRL-255N/P ECL/PECL Frequency Divider, and then measured using the PRL-550 Series, four channel ECL/PECL/LVPECL Terminator, connected to a sampling 'scope.

When the unit is driven by an AC-coupled sine wave signal in the differential input mode, the signal swing is symmetric with respect to V_TT. The peak-to peak swing of the input signal should not exceed these Common Mode limits.
