Frequently Asked Questions
What is the applicable oscillator frequency range for these modulators?
The devices support an adjustable oscillator frequency range of 100 Hz to 500 kHz.
How can I synchronize multiple units or a single unit to an external clock?
A dedicated sync input allows multiple units to be slaved or one unit to synchronize to an external system clock.
What is the maximum steady-state source or sink load current?
The recommended operating condition specifies a load current of 0 to 100 mA.
Are there specific requirements for storage and handling to prevent damage?
Since these devices have limited built-in ESD protection, they should be shorted together or placed in conductive foam when stored or handled.
