1, 7, 8, 11, 14 COMM

Connect to low impedance circuit ground.

2

INPP

Differential Input Pin. This pin needs to be dc-biased and typically ac-coupled; see Figure 3.

3

INPM

Differential Input Pin. This pin needs to be dc-biased and typically ac-coupled; see Figure 3.

4

DCPL

Bias rail decoupling capacitor connection for LO driver; see Figure 6.

5

VPOS

Positive Supply Voltage (VS), 4.5 V to 5.5 V. Ensure adequate supply bypassing for proper device operation as

shown in the Applications section.

6

PWDN

Power-Down Interface. Connect pin to ground for normal operating mode. Connect pin to supply for power-

down mode; see Figure 5.

9

LOIM

Differential Local Oscillator (LO) Input Pin. Typically ac-coupled; see Figure 4.

10

LOIP

Differential Local Oscillator (LO) Input Pin. Typically ac-coupled; see Figure 4.

12

OUTM

Open-Collector Differential Output Pin. This pin needs to be dc-biased and (usually) ac-coupled; see Figure 3.

13

OUTP

Open-Collector Differential Output Pin. This pin needs to be dc-biased and (usually) ac-coupled; see Figure 3.
