PIN DESCRIPTIONS

Pin #

Pin Name

Pin Function

1

NC

No internal connection. These pins can be left unconnected, voltage applied, or

connected to ground (recommended).

2

RF1

Device RF input or output (bi-directional). Requires a DC Block.

3

GND

Connect directly to paddle ground or as close as possible to pin with thru via.

4

NC

No internal connection. These pins can be left unconnected, voltage applied, or

connected to ground (recommended).

5

SDO

Serial Data Out. Delayed 8 clock cycles from Serial Data In.

6

NC

No internal connection. These pins can be left unconnected, voltage applied, or

connected to ground (recommended).

7

RSTb

Reset BAR. Falling Edge resets the device to Max Attenuation [D5:D0] = [000000].

8

CLK

Serial Clock.

9

CSb

Chip Select Bar. Serial Data latched into active register on Rising Edge.

10

NC

No internal connection. These pins can be left unconnected, voltage applied, or

connected to ground (recommended).

11

SDI

Serial Data Input.

12

NC

No internal connection. These pins can be left unconnected, voltage applied, or

connected to ground (recommended).

13

NC

No internal connection. These pins can be left unconnected, voltage applied, or

connected to ground (recommended).

14
