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.

VDD_LNA

LNA Supply Voltage, 1.8V. Place 0.01μF and 1μF decoupling capacitors close to VDD_LNA.

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.

DNC

Do Not Connect. Do not connect to or ground the DNC ball.

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.
