Procurement Notes

Verify the specific revision level against the datasheet Rev. 1.3.2 to ensure pinout and control voltage specifications match your design requirements. Confirm RoHS compliance status per EU 2011/65/EU standards during sourcing. Ensure thermal management strategies account for the custom CQFN package heat slug requirements.

Selection Notes

Select this component when a wide DC-32GHz bandwidth is required for analog signal distribution. Consider the adjustable peaking controls if optimizing for specific high-frequency eye diagrams. Evaluate the PCB layout complexity needed for AC versus DC coupling modes based on the chosen power supply polarity.

FAQ

How do the Ief1c and Ief3c controls affect performance?

These analog current controls adjust the peaking of the frequency response at high frequencies above 20GHz. Ief1c has a higher impact on the frequency response and improves linearity at lower control voltages.

What is the recommended power supply configuration?

The device supports either a negative supply (Vcc=0V, Vee=-3.3V) or a positive supply (Vcc=+3.3V, Vee=0V). All characteristics assume Vcc=0V and Vee=-3.3V unless otherwise specified.

Does the device have internal termination?

Yes, the I/Os support CML logic interface with internal 50Ohm termination to Vcc. External 50Ohm termination to Vcc is required for the outputs.
