15 / 141 page  Data Sheet ADMV1455 PIN CONFIGURATION AND FUNCTION DESCRIPTIONS analog.com Rev. 0 | 15 of 141 Figure 3. Pin Configuration Table 17. Pin Function Descriptions Pin No. Mnemonic Description A1, A12, J3, L1, L12 NIC Not Internally Connected. The NIC balls are not connected internally. It is acceptable to ground these balls if the application or implementation requires it. A2 VDD_LNA LNA Supply Voltage, 1.8V. Place 0.01μF and 1μF decoupling capacitors close to VDD_LNA. A3 VDD_RF RF Amplifier Supply Voltage, 1.8V. Place 0.01μF and 1μF decoupling capacitors close to VDD_RF. A4, A6, A9, B3, B4, B6, B9, C1 to C9, D3 to D5, E1 to E3, E7, E10 to E12, F3 to F6, F9, F10, G1 to G3, G7, G10 to G12, H4, H5, J4 to J10, K4, K6, K9, L4, L6, L9 GND Ground. Tie all GND balls together to a low impedance plane on the PCB. A10 GPO_G4 General-Purpose Digital Output Ball Gain 4. Active high, 1.8V logic. This ball can be left floating. Do not ground this ball. A11 VDD_MIX Mixer Supply Voltage, 1.8V. Place 0.01μF and 1μF decoupling capacitors close to VDD_MIX. B1 DNC Do Not Connect. Do not connect to or ground the DNC ball. B2 CM_REF I/Q Baseband Common-Mode Reference Voltage Input. When the internal common-mode voltage reference is used, the CM_REF ball can float. When setting the common-mode voltage externally, use the CM_REF ball and place a 0.01μF decoupling capacitor close to CM_REF. Do not ground CM_REF. |
