Zarlink Semiconductor Inc.
200ns is the maximum phase continuity of the ZL30409 from Holdover Mode to Normal Mode (with or
without TIE Corrector Circuit)
When 10 Normal to Holdover to Normal mode change sequences occur without MTIE enabled, and in each case
holdover was entered for 2s, each mode change sequence could still account for a phase change as large as
350ns. However, there would be no accumulated phase change, since the input to output phase is re-aligned after
every Holdover to Normal state change. The overall MTIE would only be 350ns.
Reset Circuit
A simple power up reset circuit with about a 50us reset low time is shown in Figure 10. Resistor R
P
is for protection
only and limits current into the RST pin during power down conditions. The reset low time is not critical but should
be greater than 300ns.
