RX_QMC_GAIN_PH_SYNC_DIS – Disables Syncing of Rx QMC Gain Phase Correction.
This takes effect only when RX_GLOBAL_SYNC_DIS is set.
RX_GLOBAL_SYNC_DIS – When set, disables global syncing of RX signal chain. When cleared, a rising
edge on the selected sync source causes RX blocks to be synced.

RX_CMIX_SYNC_SRC – Specifies the sync source for the RX Coarse mixer. When cleared, SYNC pin is
used as the sync source . When set, a rising edge on serial interface bit RX_CMIX_SER_IF_SYNC in
Register
0x16A
is
used
as
the
sync
source
for
RX
CMIX.
This
is
applicable
when
RX_GLOBAL_SYNC_DIS is set, and RX_CMIX_SYNC_DIS is cleared.
RX_DIV_SYNC_SRC – Specifies the sync source for the RX Divider. When cleared, SYNC pin is used as
the sync source . When set, a rising edge on serial interface bit RX_DIV_SER_IF_SYNC in register 0x16A
is used as the sync source for RX Divider. This is applicable when RX_GLOBAL_SYNC_DIS is set and
RX_DIV_SYNC_DIS is cleared.
RX_QMC_OFF_SYNC_SRC – Specifies the sync source for RX QMC Offset Correction. When cleared,
SYNC pin is used as the sync source . When set , a rising edge on serial interface bit
RX_QMC_OFF_SER_IF_SYNC in register 0x16A is used as the sync source for RX QMC Offset
Correction. This is applicable when RX_GLOBAL_SYNC_DIS is set and RX_QMC_OFF_SYNC_DIS is
cleared.
RX_QMC_GAIN_PH_SYNC_SRC – Specifies the sync source for RX QMC Gain Phase Correction. When
cleared, SYNC pin is used as the sync source. When set, a rising edge on serial interface bit
RX_QMC_GAIN_PH_SER_IF_SYNC in register 0x16A is used as the sync source for RX QMC Gain
Phase
Correction.
This
is
applicable
when
RX_GLOBAL_SYNC_DIS
is
set
and
RX_QMC_GAIN_PH_SYNC_DIS is cleared.
RX_GLOBAL_SYNC_SRC – Specifies the sync source for RX. When cleared, SYNC pin is used as the
sync source. When set, a rising edge on serial interface bit RX_GLOB_SER_IF_SYNC in register 0x16A
is used as the sync source for RX. This is applicable when RX_GLOBAL_SYNC_DIS is cleared.

RX_CMIX_SER_IF_SYNC – A rising edge on this bit is used as the sync source for RX CMIX. This is
applicable
when
RX_GLOBAL_SYNC_DIS
is
set,
and
RX_CMIX_SYNC_DIS
is
cleared,
and
RX_CMIX_SYNC_SRC specifies serial interface bit to be the sync source for the RX CMIX.
RX_DIV_SER_IF_SYNC – A rising edge on this bit is used as the sync source for RX Divider. This is
applicable
when
RX_GLOBAL_SYNC_DIS
is
set,
and
RX_DIV_SYNC_DIS
is
cleared,
and
RX_DIV_SYNC_SRC specifies serial interface bit to be the sync source for the RX Divider.
RX_QMC_OFF_SER_IF_SYNC – A rising edge on this bit is used as the sync source for RX QMC Offset
correction
block.
This
is
applicable
when
RX_GLOBAL_SYNC_DIS
is
set,
and
RX_QMC_OFF_SYNC_DIS is cleared, and RX_QMC_OFF_SYNC_SRC specifies serial interface bit to be
the sync source for the RX QMC Offset correction.
RX_QMC_GAIN_PH_SER_IF_SYNC – A rising edge on this bit is used as the sync source for RX QMC
Gain Phase correction block. This is applicable when RX_GLOBAL_SYNC_DIS is set, and
RX_QMC_GAIN_PH_SYNC_DIS is cleared, and RX_QMC_GAIN_PH_SYNC_SRC specifies serial
interface bit to be the sync source for the RX QMC Gain Phase correction.
