PLL phase-locked loop
ppm parts per million
pseudodifferential
channels
pseudodifferential channels are all referred to a common ground, but this
ground is not directly connected to the computer ground. Often this
connection is made by a relatively low value resistor to give some
isolation between the two grounds.
