FUNCTION
A1
IN1
Channel 1 Input. Connect to a 4.7nF coupling capacitor.
A2
ZF1
Channel 1 Active Impedance Matching Line. AC-couple to IN1 with a 2.2nF capacitor.
A3, L6, M6
VCC3
3.3V Power-Supply Voltage. Bypass to GND with a 0.1FF capacitor as close as possible to the part.
A4
CI+
8-Channel CW Positive In-Phase Output. Connect to 11V with a 120I external resistor.
A5
CQ+
8-Channel CW Positive Quadrature Output. Connect to 11V with a 120I external resistor.
A6
LO+
Positive CW Local Oscillator Input. This clock is then divided in the beamformer.
A7, B8,
L7, M7
AVDD
1.8V Analog ADC Power-Supply Voltage. Connect AVDD to a 1.7V to 1.9V power supply. Bypass
AVDD to GND with a 0.1FF capacitor as close as possible to the device.
A8
N.C.
No Connection. Internally not connected.
A9
REFIO
I/O Reference (for Internal Calibration)
A10
CWD
VGA/CW Mode Select. Set CWD low to enable the VGAs and disable the CW mixers. Set CWD high
to enable the CW mixers and disable the VGAs.

Power-Down (Nap or Sleep Mode Programmable through Serial Interface)
B11
OUT1+
Channel 1 Positive LVDS Output
B12
OUT1-
Channel 1 Negative LVDS Output
C1
INC2
Channel 2 Clamp Input. Connect to the source side of the coupling capacitor.
C2
IN2
Channel 2 Input. Connect to a 4.7nF coupling capacitor.
