Function and Connection
Control signals for pulser. P outputs control positive pulses and N outputs
control negative pulses..
PLL Reference Clock PLUS Input, LVDS compatible or Single-Ended LV
CMOS input, programmable through 4-Wire Serial Interface (Register
1Bh[0])
PLL Reference Clock MINUS input, LVDS compatible. For Single-Ended
PLL Reference Clock operation, tie this pin to AGND or VDDA.
1 = Beamformer starts firing
0 = Beamformer ceases firing
Voltage range 0.8-1.2V for tuning internal PLL noise performance. Under
normal conditions, 0.94V is recommended.
