Serial Port Data Input. Data input to program the serial shift registers.
Serial Port Data Clock. Clock input for programming the serial shift registers.
CW Mode Select Input 1. Input for programming beamforming mode 1, 2, 3, or 4. See Table 1 for
mode programming details.
CW Mode Select Input 2. Input for programming beamforming mode 1, 2, 3, or 4. See Table 1 for
mode programming details.
VGA Clamp Mode Enable. Drive VG_CLAMP_MODE low to enable VGA clamp mode. VGA output is
clamped at typically 2.4V
Serial Port Load. Loads the data from the serial shift registers into the I/Q phase dividers. Pull LOAD
bus from high to low and from low to high for programming the I/Q phase dividers.
CW Mixer Noninverting Differential Quadrature Output. CW Mixer output for eight quadrature mixers
combined.
