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. Rev.
