DS280BR820は非常に消費電力が低く高パフォーマンスの8チャネル・リニア・イコライザーで、マルチレート、マルチプロトコルで最大28Gbpsのインターフェイスをサポートします。バックプレーン、フロントポート、チップ・ツー・チップのアプリケーションにおいて、高速シリアル・リンクの到達範囲を拡張し、堅牢性を強化するために使用されます。
DS280BR820の均等化の直線性から、送信信号の特性が保持され、ホストとリンク・パートナーのASICとが、送信イコライザーの係数を自由にネゴシエーションできるようになります(100G-CR4/KR4)。このリンク・トレーニング・プロトコルへの透過性により、レイテンシへの影響を最小限に抑えながら、システム・レベルの相互運用性を向上できます。各チャネルは独立に動作するため、DS280BR820は個別のレーン・フォワード・エラー訂正(FEC)パススルーをサポートできます。
DS280BR820はパッケージの寸法が小さく、高速信号エスケープが最適化され、Retimerポートフォリオとピン互換なため、高密度のバックプレーン・アプリケーションに理想的です。単純化された均等化制御、低い消費電力、非常に低い付加的ジッタから、100G-SR4/LR4/CR4などのフロントポート・インターフェイスに適しています。8mm×13mmの小さなフットプリントのため、QSFP、SFP、CFP2/CFP4、CDFPなど各種の標準フロントポート・コネクタに簡単に収まり、ヒートシンクの必要もありません。
ACカップリング・コンデンサ(RX側)が内蔵されているため、PCB上に外付けのコンデンサが必要ありません。DS280BR820は単一電源で、必要な外部コンポーネントも最小限です。これらの特長により、PCBの配線の複雑性と、部品表(BOM)コストを低減できます。
より到達範囲の長いアプリケーション用には、ピン互換のRetimerデバイスを利用可能です。
DS280BR820はSMBus経由、または外付けのEEPROMにより構成可能です。単一のEEPROMを、最大16個のデバイスで共有できます。

Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as "components") are sold subject to TI's terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI's terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed.
TI assumes no liability for applications assistance or the design of Buyers' products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers' products and applications, Buyers should provide adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI's goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or "enhanced plastic" are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
