receivers is 2 V. If the companion driver is not used, it should
be terminated with either a proper AC or DC termination. This
latter example of AC coupling a single-ended LVPECL signal
can be used to measure single-ended LVPECL performance
using a spectrum analyzer or phase noise analyzer. When
using most RF test equipment no DC bias point (0 VDC) is
required for safe and proper operation. The internal 50 Ω ter-
mination the test equipment correctly terminates the LVPECL
driver being measured as shown in Figure 15. When using
only one LVPECL driver of a CLKoutX/CLKoutX* pair, be sure
to properly terminated the unused driver.
