Phase Locked Loops (PLLs)
This table lists the performance characteristics of the low and high frequency phase locked loops over
the full range of process variation, operating temperature and supply voltage.

The low frequency PLL requires external low pass filter components connected to the FIL pin, as
shown in Applications Information. The filter consists of a 2.2nF capacitor from FIL to AGND, in parallel
with a 68nF capacitor and an 8.2kΩ resistor in series.
External Clock Source
If an external clock source is used as the main system clock for the eCOG1X, the following parameters
apply.
