Substitute Part Grouping Explanation

Substitution for the AX7MCF2-2000.0000C is determined by strict equivalence across the following critical parameters:

Frequency: 2 GHz
Output Type: CML
Supply Voltage: 1.8V
Function: Enable/Disable
Package Type: 8-SMD, No Lead
Package Dimensions: 7.00mm x 5.00mm
Operating Temperature Range: -40°C ~ 85°C
