[1] Enabling B4 disables B3, the minimum attenuation is 16 dB
Control Interface:
The gain of HMC680LP4(E) is controlled by adjusting the state of the attenuator. The attenuator has a 5-bit parallel
CMOS/TTL compatible interface. State of the attenuator can be set with respect to the truth table above.
Power on sequence:
The ideal power up sequence is: GND, Vdd, Digital inputs, RF inputs. Relative order of the digital inputs is not
important as long as they are powered after VDD/GND.
