[9] Measured with a 100 Ω external resistor termination, resulting in 50Ohm effective input impedance.. See “Reference Input Stage” for more details.
Full FOM performance up to maximum 3.3 Vpp input voltage.
[10] Measured with a 100 Ω external termination AC coupled on HMC703LP4E evaluation board, as in Figure 35.
[11] Measured with a 100 Ω external termination AC coupled on HMC703LP4E evaluation board, as in Figure 37.
