Hi team,
For MDI component ratings -
- There are some differences between TI documents (datasheet, app note) in terms of DC blocking cap tolerance and ESD shunt resistor tolerance. Could you please comment which tolerance customer should follow?
- There is no BOM info in EVM guide and it will be good to share the EVM BOM for complete info such as tolerance, voltage rating and power rating.
- There are differences between TI and OPEN Alliance recommendation - TI's rating is higher resulting in larger and more expensive components. Could you please comment?
- Ultimately, could you please recommend tolerance, voltage/power ratings for all the MDI components for customer to pass OPEN Alliance compliance test?
| Value | TI EVM R & C | TI EVM Rating | TI Datasheet Rating (Table 9-1) | TI App Note SNLA389A (Table 2-1) | TI Recommendation | OPEN Alliance | |
| DC Blocking Cap | 0.1uF | C40 & C84 | 100V | 10% | 100V 1% | ?V ?% | 50V 10% |
| MDI Coupling Cap | 4.7nF | C93 | 1kV | 10% | - | ?V ?% | 50V 10% |
| Common-Mode Termination Res | 1kohm | R109 & R110 | - | 1% | 0.75W 1% | ?W ?% | 0.4W 1% |
| ESD Shunt Res | 100kohm | R113 | - | 10% | 0.125W 5% | ?W ?% | 0.1W 10% |
