The bipolar analog output XTIP/XRING can be enabled or disabled using the
XOE pin. This feature allows switching between multiple XTIP/XRING outputs
that are tied together.
In any window of 17 consecutive primary rate cycles, the maximum variation in
pulse amplitude in the absence of 60 Hz variations is <200 mV. The maximum
variation in pulse width at half amplitude is <20 ns.
