Below about 1 MHz, the input should be dc-coupled. Care should be taken to match V
This is the difference between any two similar delay paths while operating at the same voltage and temperature.

Test Conditions/Comments
Differential input
High frequency distribution (VCO divider)
Distribution only (VCO divider bypassed)
Measured at 2.4 GHz; jitter performance is
improved with slew rates > 1 V/ns
Larger voltage swings may turn on the
protection diodes and may degrade jitter
performance
Self-biased; enables ac coupling
With 200 mV p-p signal applied; dc-coupled
CLK ac-coupled; CLK ac-bypassed to RF ground
Self-biased
Test Conditions/Comments
Termination = 50 Ω to V
Differential (OUT, OUT)
Using direct to output; see Figure 16
