Bit
Name
Function
BCRA0
MCLKDIV
MCLK Divider. When this bit is
set to 0, the internal MCLK has
the same value as the external
MCLK. When this bit equals 1,
the external MCLK is divided by
2 within the AD7729 so that the
device operates at half the exter-
nal clock frequency.
BCRA1
RxAUTOCAL
Selects AutoCal when set to 1
and UserCal when set to 0.
BCRA2
RxEXTCAL
When set to 1, the Rx calibration
operates in external mode i.e.,
the I and Q analog inputs remain
connected to the pins during the
Rx autocalibration routine.
BCRA3
RxPOWER0
This bit, in conjunction with
RxPOWER1, is used to reduce
the analog current consumption
of the ADCs.
BCRA4
RxPOWER1
This bit, in conjunction with
RxPOWER0, is used to reduce
the analog current consumption
of the ADCs.

BCRA6
RxON
Power-on for the receive section
of the AD7729.

Baseband Reset.

Bits RxPOWER0 and RxPOWER1 are used to reduce the ana-
log current consumption of the ADCs. The part is specified in
Power Mode 1. In Power Mode 2, the MCLK needs to be less
than 10 MHz. The performance of the part will then be compa-
rable to the performance in Power Mode 1 except that the ADC
current will now be less than 9.5 mA.
