MASTER / SLAVE CONFIGURATION
Master / Slave configuration is only supported by the T0 path of the
device.
Two devices should be used together in order to:
Enable system protection against single chip failure;
Guarantee no service interrupt during system maintenance, such
as software or hardware upgrade.
Of the two devices, one is configured as the Master and the other is
configured as the Slave. The configuration is made by the MS/SL pin
and the MS_SL_CTRL bit (b0, 13H), as shown in Table 28:
In this application, all the output clocks derived from the T0 selected
input clock and the frame sync output signals from the two devices are
at the same frequency offset and phase. Refer to Chapter 3.13.2 Frame
The difference between the Master and the Slave is: in the Master,
the IN5 should not be selected by the T0 DPLL; in the Slave, the follow-
ing functions are automatically forced:
The T0 selected input clock is IN5;
T0 PBO is disabled;
T0 DPLL operates at the acquisition bandwidth and damping fac-
tor;
EX_SYNC1 is used for synchronization;
T0 DPLL operates in Locked mode.
In the Slave, the corresponding registers of the above forced func-
tions can still be configured, but their configuration does not take any
effect. The frequency of the T0 selected input clock IN5 is recommended
to be 6.48 MHz.
