Description

SEN

SPI Serial Enable. SEN is a high impedance pin with a logic of 1.8 V.

2, 3

I_P, I_N

Negative (I_N) and Positive (I_P) Differential BB I Outputs. These pins are dc-coupled.

4, 6

IF_I, IF_Q

IF I and IF Q Single-Ended Complex Quadrature Outputs. These pins are dc-coupled to GND, and

each pin is matched to 50 Ω.

5, 13, 17, 19, 25, 28

GND

Ground.

7, 8

Q_N, Q_P

Positive (Q_P) and Negative (Q_N) Differential Baseband Q Outputs. These pins are dc-coupled.

SDO

SPI Serial Data Output.

VCC_IF_BB

3.3 V Power Supply for BB and IF Section. Place a 100 pF, 0.01 μF, and a 10 μF capacitor close to this

pin.

VDET

Square Law Detector Output Voltage.

VCC_VGA

3.3 V Power Supply for RF Amplifier. Place a 100 pF, 0.01 μF, and a 10 μF capacitor close to this pin.

VCTRL

RF VVA Control Voltage. The voltage on this pin ranges from 1.8 V (minimum gain) to 0 V (maximum

gain). Refer to the ADMV1014-EVALZ user guide for the external component requirements.

VCC_VVA

1.8 V Power Supply for VVA Control Circuit. Place a 100 pF, 0.01 μF, and a 10 μF capacitor close to

this pin.

VCC_LNA_3P3

3.3 V Power Supply for LNA. Place a 100 pF, 0.01 μF, and a 10 μF capacitor close to this pin.

RF_IN

RF Input. This pin is dc-coupled internally with a choke to GND, and matched to 50 Ω, single-

ended. A dc input above 0 V requires external ac coupling.

VCC_LNA_1P5

1.5 V Power Supply for Low Noise Amplifier (LNA). Place a 100 pF, 0.01 μF, and a 10 μF capacitor

close to this pin.

VCC_BG

3.3 V Power Supply for Band Gap Circuit. Place a 100 pF, 0.01 μF, and a 10 μF capacitor close to this

pin.

RST

SPI Reset. Connect this pin to logic high for normal operation.

BG_RBIAS

Bang Gap Circuit External High Precision Resistor. Place a 1.1 kΩ, high precision resistor shunt to

ground close to this pin.

VCC_QUAD

3.3 V Power Supply for Quadruple. Place a 100 pF, 0.01 μF, and a 10 μF capacitor close to this pin.
