DC INTERFACES
BIASING AND DECOUPLING (VPOS, DCPL)
VPOS is the power supply connection for the internal bias circuit
and the LO driver. Bypass this pin closely to GND with a
capacitor in the range of 0.01 μF to 0.1 μF. The DCPL pin
provides access to an internal bias node for noise bypassing
purposes. Bypass this node to COMM with 0.1 μF.
POWER-DOWN INTERFACE (PWDN)
The AD8343 is active when the PWDN pin is held low; other-
wise the device enters a low-power state as shown in Figure 51.

POWER-DOWN VOLTAGE (V)
Figure 51. Device Current vs. PWDN Voltage
To assure full power-down, the PWDN voltage must be within
0.5 V of the supply voltage at VPOS. Normal operation requires
that the PWDN pin be taken at least 1.5 V below the supply
voltage. The PWDN pin sources about 160 μA when pulled to
GND (see the Pin Configuration and Function Descriptions
section). It is not advised to leave the pin floating when the
device is disabled; a resistive pull-up to VPOS is the minimum
suggestion.
The AD8343 requires about 2.2 μs to turn off when PWDN is
show typical characteristics (they vary with bypass component
values). Figure 54 shows the test configuration used to acquire
these waveforms.
