MAX9601 Evaluation Kit Evaluates: MAX9601 General Description Features The MAX9601 evaluation kit (EV kit) is a fully assem- S -2.2V to +3V Input Range with +5V/-5.2V Supplies bled and tested surface-mount PCB that evaluates the S -1.2V to +4V Input Range with +6V/-4.2V Supplies MAX9601 dual-channel PECL output comparators. It S SMA Connectors to Access Differential Inputs and can be used to evaluate the MAX9601s performance in Outputs tracking high-fidelity narrow pulses, as well as conform its low-propagation delay and delay dispersion. The S Differential PECL Outputs differential input stage accepts a wide range of signals S Latch Enable in the common-mode range from (VEE + 3V) to (VCC - S Adjustable Hysteresis 2V). The outputs are complementary digital signals with S Output Terminated for Interfacing with a 50I external components necessary to observe the PECL Oscilloscope Input serial-data output on a 50I input oscilloscope. The board also provides layout options that allow the output S Allows Alternate Output Terminations termination to be modified easily for alternate output S Fully Assembled and Tested terminations, such as +5V PECL and high impedance or AC-coupled level translation. The EV kit features test points to control the complementary latch-enable control Ordering Information inputs. The EV kit also provides resistor footprints to evaluate the MAX9601s adjustable hysteresis feature. PART TYPE MAX9601EVKIT+ EV Kit +Denotes lead(Pb)-free and RoHS compliant.
