Description

1, 18

NC

No Connect. These pins are not connected internally; however, all data shown herein was measured with these

pins connected to RF/dc ground externally.

2, 5, 14, 17

GND

Ground Pin. Connect these signal grounds to 0 V. See Figure 3 for the interface schematic.

3

INP

Positive Differential RF Input Pin. See Figure 4 for the interface schematic.

4

INN

Negative Differential RF Input Pin. See Figure 4 for the interface schematic.

6

EN

Enable Pin for the Time Delay. For normal operation, leave this pin open or apply 3.3 V. To disable the HMC911,

apply 0 V. When disabled, the total current consumption drops to 15 mA. See Figure 5 for the interface schematic.

7, 8, 11, 13

Supply Grounds. Connect these pins to 0 V. See Figure 6 for the interface schematic.

9

Positive Differential Time Delay Control Pin. See Figure 7 for the interface schematic.

10

Negative Differential Time Delay Control Pin. See Figure 7 for the interface schematic.

12

Output Amplitude Control Pin. See Figure 8 for the interface schematic.

15

QN

Negative Differential RF Output Pin. See Figure 9 for the interface schematic.

16

QP

Positive Differential RF Output Pin. See Figure 9 for the interface schematic.

19 to 24

Positive Supply Pins. See Figure 10 for the interface schematic.

EPAD

Exposed Pad. Connect the exposed pad to RF/dc ground.
