Data Sheet

Zarlink Semiconductor Inc.
15.1.3 Slave Mode
In the Slave Mode, the ZL50030 is phase locked to the “A Clocks”. If the “A Clocks” become unreliable, the device
goes to stable Holdover Mode until it makes a Stratum 4 Enhanced compatible switch to the “B Clocks”. The
ZL50030 will perform all required functionality as long as the “A Clocks” and the “B Clocks” conform to the Telcordia
GR-1244-CORE jitter specifications.
In addition, the device can be used to generate a NREFo reference from its network references, LREF0-3. In most
systems NREFo is connected to either CT_REF1 or CT_REF2.
While the device is in Slave Mode and the “A Clocks” or the “B Clocks” do not recover, the designated slave can be
promoted to secondary master by system software. In that case, the network reference can be used as the
secondary reference.
Table 21 on page 49 shows how to program the DOM1 and DOM2 registers to enable the Slave Mode of the
ZL50030.
