CW Mixer Output Summation
The outputs from the octal mixer array are summed inter-
nally to produce the total CWD summed beamformed
signal. The octal array produces eight differential quad-
rature (Q) outputs and eight differential in-phase (I) out-
puts. All quadrature and in-phase outputs are summed
into single I and Q differential current outputs
(CW_QOUT+, CW_QOUT-, CW_IOUT+, CW_IOUT-).
LO Phase Select
The LO phase dividers can be programmed through
the shift registers to allow for 4, 8, or 16 quadrature
phases for a complete CW beamforming solution.
CWD Beamforming Modes
There are four separate modes of operating the CWD
beamformer. See Table 1 for a summary of the different
modes of operation. The mode of operation can be
selected by the CW_M1 and CW_M2 logic inputs.
Phase generation is controlled through the serial inter-
face. See the
Serial Interface section in the Applications
Information section for details on how to program for
different quadrature phases.
Mode 1
For mode 1 operation, the LO_LVDS input frequency is
typically 16 x fLO. As the CWD LO frequency range is
1MHz to 7.5MHz, the input frequency ranges from
16MHz to 120MHz. This high LO clock frequency
requires a differential LVDS input. The 16 x fLO input is
then divided by 16 to produce 16 phases. These 16
phases are generated for each of the 8 channels and
programmed for the selected phase by a serial shift
register. Each channel has a corresponding 5-bit shift
register, which is used to program the output phase of
the divide-by-16 circuit. The first 4 bits of the shift regis-
ter are for programming the 16 phases; the fifth bit turns
each channel on/off individually. For mode 1, set both
CW_M1 and CW_M2 to a logic-low. See Table 2.
