MAX40025C
MAX40025 Evaluation Kit
General Description
Quick Start
The MAX40025 evaluation kit (EV kit) is a fully assembled
electrical demonstration kit that provides a proven design
to evaluate the MAX40025 ultra-low 280ps propagation
delay, ultra-low dispersion comparator. The board
provides layout options that allow the input termination to
be easily modified for alternative input terminations. The
comparator outputs are designed to drive low voltage
differential signal outputs (LVDS). The LVDS outputs help
minimize power dissipation and interfaces directly with
high speed interconnect devices, FPGAs and CPUs. The
MAX40025 comparator is ideal for time of flight distance
measurement applications.
Required Equipment
● MAX40025 EV kit
● 6 matched-length SMA cables (preferably up to
18GHz capable), 2 feet, or less, in length
● +3.6V, 100mA DC power supply (V /+SUPPLY)
CC
● High-speed signal generator with differential outputs
capable of generating square waves with < 500ps
rise times. (e.g., HP 8131A)
● High-speed oscilloscope with 50Ω termination
Procedure
This evaluation kit demonstrates the MAX40025CAWT+ in
6-pin wafer-level package (WLP). For other available pin-
compatible option (MAX40025AAWT+), contact factory.
The MAX40025 EV kit is fully assembled and tested.
Follow the steps below to verify board operation.
Caution: Do not turn on power supply until all connections
are completed.
