Preliminary Data Sheet #: TM061 Page 27 of 48 Rev: P06 Date: 11/22/04 © Copyright 2001 The Connor-Winfield Corp. All Rights Reserved Specifications subject to change without notice Performance Specifications continued Wander Generation Characteristics – MTIE (10 Hz single-pole LPF applied) Wander Generation Characteristics – TDEV (10 Hz single-pole LPF applied) 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): 1 10 100 1000 0.1 1 10 100 1000 10000 100000 Observation Time (sec) GR-1244-CORE, R5-5 0.01 0.1 1 10 100 0.01 0.1 1 10 100 1000 10000 100000 Integration Time (sec) GR-1244-CORE, R5-4 |
