Substitute Part Grouping Explanation
Substitution of the DS25MB100TSQE/NOPB is determined by strict equivalence across the following critical parameters:
- Data Rate (Max): 2.5Gbps
- Number of Channels: 1 x 1:2, 2:1
- Input Signal Type: CML
- Output Signal Type: CML
- Delay Time: 1.0ns
- Signal Conditioning: Input Equalization, Output Pre-Emphasis
- Voltage - Supply: 3.135V ~ 3.465V
- Operating Temperature: -40°C ~ 85°C
- Package / Case: 36-WFQFN Exposed Pad
- Mounting Type: Surface Mount
The DS25MB100TSQX/NOPB meets all these criteria and is classified as a parametric equivalent. The primary distinction between the main part and its substitute is packaging format and product status.
