THVD1452: RL 120 ohm Criteria

Mike Yu

Part Number: THVD1452

Hi Team,

The customer had reference our EVM schematic, they place 120 ohm as the RL value.

The question is that do we have RL 120 ohm criteria? I had checked the DS. We only have RL 54 ohm criteria in it.

Best regards,

Two termination resistors in parallel, with a tolerance of 10 %, results in a total load of 54 Ω.

Mike,

As Clemens said, the overall termination resistance requirement is the parallel combination of 100-120 ohm resistors on the bus.
