Free Run Frequency Accuracy – Free Run frequency accuracy is the maximum fractional frequency offset while in
Free Run mode. It is determined by the accuracy of the TCXO/OCXO. All TCXO/OCXO devices recommended for use
with the STC3800 in the application section will meet GR-1244 and ITU G.813 requirements.
Hold Over Frequency Stability – Hold Over frequency stability is the maximum fractional frequency offset while in
Hold Over mode. It is determined by the stability of the TCXO/OCXO. All TCXO/OCXO devices recommended for use
with the STC3800 in the application section will meet GR-1244 and ITU G.813 requirements.
Wander Generation – Wander generation is the process whereby wander appears at the output of a clock in the
absence of input wander. The STC3800 wander generation characteristics, MTIE and TDEV, are shown below, along
with the requirements masks (bandwidth = 0.39 Hz):
