This is achieved by another level of encoding which takes the raw pulses and translates them into a protocol for transmission. This article discusses the proper transmission protocol for that application and the encoder choice that is best for that protocol.

As such, they are required to be accurate and precise over time. Of course, the "perfect" oscillator only exists in theory, so the problem for designers is the right oscillator to meet the design objectives.
