Substitute Part Grouping Explanation
Substitution of the CDCE937PWRG4 is determined by strict equivalence across the following critical parameters:
- Maximum frequency: 230MHz
- Supply voltage range: 1.7V ~ 1.9V
- Operating temperature range: -40°C ~ 85°C
- Package type: 20-TSSOP (0.173", 4.40mm Width)
- Input configuration: LVCMOS, Crystal
- Output configuration: LVCMOS
- Number of circuits: 1
- Input-to-output ratio: 1:7
- PLL with bypass capability: Yes
- RoHS3 compliance
- MSL rating: 1 (Unlimited)
The CDCE937PWR meets all these parameters and qualifies as a parametric equivalent. The primary distinction is packaging format and product status.
