Overview

KNXトランシーバ・ツイスト・ペア・ネットワーク（KNX TP1-256）NCN5121はレシーバ-トランスミッタ集積回路（IC）として使用できます。NCN5121にはPHY層とMAC層のいずれも組み込まれており、バス上でデータの送受信を処理します。未調整バス電圧から安定化電圧を生成し、自己の電源ニーズを満たすのに加え、外部デバイスへも電源を供給します。NCN5121はバスとの間での結合/分離の安全性を保証します。さまざまなモニタ（バス電圧、電流、温度...）がアナログ・ピン経由で使用できます。

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
