7SYS_INIT
System Initialization Status.
During power up the device copies the content of the NVM into RAM and performs a system
initialization. The device is not operational until initialization is complete. It is not recom-
mended to read or write registers in RAM through the I2C interface until initialization is com-
plete. An interrupt will be triggered (INTR pin = 0, Si5351C only) during the system
initialization period.
0: System initialization is complete. Device is ready.
1: Device is in system initialization mode.
6LOL_B
PLLB Loss Of Lock Status.
Si5351A/C only. PLLB will operate in a locked state when it has a valid reference from CLKIN
or XTAL. A loss of lock will occur if the frequency of the reference clock forces the PLL to
operate outside of its lock range as specified in Table 3, or if the reference clock fails to meet
the minimum requirements of a valid input signal as specified in Table 4. An interrupt will be
triggered (INTR pin = 0, Si5351C) during a LOL condition.
0: PLL B is locked.
1: PLL B is unlocked. When the device is in this state it will trigger an interrupt causing the
INTR pin to go low (Si5351C only).
5LOL_A
PLL A Loss Of Lock Status.
PLL A will operate in a locked state when it has a valid reference from CLKIN or XTAL. A loss
of lock will occur if the frequency of the reference clock forces the PLL to operate outside of
its lock range as specified in Table 3, or if the reference clock fails to meet the minimum
requirements of a valid input signal as specified in Table 4. An interrupt will be triggered
(INTR pin = 0, Si5351C only) during a LOL condition.
0: PLL A is operating normally.
1: PLL A is unlocked. When the device is in this state it will trigger an interrupt causing the
INTR pin to go low (Si5351C only).
4LOS
CLKIN Loss Of Signal (Si5351C Only).
A loss of signal status indicates if the reference clock fails to meet the minimum requirements
of a valid input signal as specified in Table 4. An interrupt will be triggered (INTR pin = 0,
Si5351C only) during a LOS condition.
0: Valid clock signal at the CLKIN pin.
1: Loss of signal detected at the CLKIN pin.
