    Operating with a 2.5V core to meet low-voltage and lowpower requirements, the KS8721BL and KS8721SL are 10BASE-T/100BASE-TX/FX Physical Layer Transceivers that use MII and RMII interfaces to transmit and receive data. They contain 10BASE-T Physical Medium Attachment (PMA), Physical Medium Dependent (PMD), and Physical Coding Sub-layer (PCS) functions. The KS8721BL/SL also have on-chip 10BASE-T output filtering. This eliminates the need for external filters and allows a single set of line magnetics to be used to meet requirements for both 100BASE-TX and 10BASE-T. The KS8721BL/SL automatically configure themselves for 100 or 10Mbps and full- or half-duplex operation, using an on-chip auto-negotiation algorithm. They are the ideal physical layer transceiver for 100BASE-TX/ 10BASE-T applications.

      A: To ensure transaction security and accommodate standard corporate purchasing workflows, we support secure international Telegraphic Transfers (T/T Wire), major corporate Credit Cards, PayPal, and Letter of Credit (L/C) frameworks for large-scale procurement contracts.

    • Q: How can I verify that a product on OKmarts is brand new and not "New Old Stock" (NOS) with degraded internal components?

      A: Upon request, we provide standard manufacturer compliance documentation, including Certificates of Conformance (CoC), factory inspection reports, and CE/RoHS certification data sheets to ensure alignment with international regulatory and safety standards.
