ADL5375

Rev. 0 | Page 21 of 32

OUTPUT DISABLE

The ADL5375 incorporates an output disable pin feature that

shuts down the output amplifier stage to isolate the modulator

from the load. This feature is enabled (output is disabled) when

the voltage on the DSOP exceeds 2 V. The feature is disabled

(output not enabled) when the DSOP pin is either tied to

ground or left unconnected.

Asserting DSOP further reduces LO leakage (see Figure 27 and

Figure 52) and drives the broadband noise of the device down

to just above the KT (thermal) noise level. Asserting DSOP also

reduces the supply current of the ADL5375 from 200 mA to

131 mA.

The time delay between when the DSOP pin is forced to ground

and the output power is restored is approximately 200 ns. The

time delay between when the DSOP pin is forced to the positive

supply voltage and the output shuts off is under 100 ns.
