Description

1, 3 to 7, 9

GND

Ground. The GND pins must be connected to the RF and DC ground of the PCB.

2

ATTIN

Attenuator Input. No DC blocking capacitor is necessary when the RF line potential is equal to 0 V DC. See Figure 5 for the

interface schematic.

8

ATTOUT

Attenuator Output. No DC blocking capacitor is necessary when the RF line potential is equal to 0 V DC. See Figure 5 for the

interface schematic.

10

VSS

Negative Supply Input. See Figure 8 for the interface schematic.

11

D0

Parallel Control Input for 16 dB Attenuation Bit. See the Theory of Operation section for more information. See Figure 6 for the

interface schematic.

12

VDD

Positive Supply Input. See Figure 7 for the interface schematic.

EPAD

Exposed Pad. The exposed pad must be connected to the RF and DC ground of the PCB.
