Substitute Part Grouping Explanation

Substitution of the CDCVF857DGGG4 is determined by strict equivalence across the following critical parameters:

  • Package Type: 48-TFSOP (0.240", 6.10mm Width) — physical and electrical compatibility
  • Frequency Specification: 220MHz maximum — functional performance requirement
  • Input/Output Signaling: SSTL-2 differential — interface compatibility
  • Input:Output Ratio: 2:11 — clock multiplication factor
  • Supply Voltage Range: 2.3V ~ 2.7V — power supply compatibility
  • Operating Temperature Range: -40°C ~ 85°C — environmental specification
  • Regulatory Compliance: ROHS3 Compliant, REACH Unaffected — legal and environmental requirements

The CDCVF857DGG meets all these criteria and qualifies as a direct substitute for the CDCVF857DGGG4.
