Description

The PRL-252-2 is an AC-coupled I/O, f/2 frequency divider with complementary outputs. It has internal 50 Ω I/O terminations, and is capable of running at input frequencies in excess of 12 GHz. It is ideal for applications where a high frequency divider or pre-scalar is needed for triggering or down-sampling. Applications for the PRL-252-2 include data acquisition, test, measurement, R&D, and system integration.

The unit includes an AC adapter for ready-to-use convenience on the bench or in a system. All I/O connectors are SMA. The extruded aluminum housing is suitable for mounting with the optional brackets.

* All measurements are made with outputs terminated into 50 Ω.
Notes:
(1) The output rise and fall times are measured with with all inputs terminated into 50 Ω/VTT.
(2) Jitter specification limited by PRL production test equipment. Lab characterization shows typical jitter performance of < 2 ps one-sigma RJ.
