The VSC7281VT-03 offers advanced lane-to-lane isolation, low-power operation, and integrated control-signal conditioning. It is a three-channel serial transceiver targeted for high-speed applications such as backplane, RAID, ASIC interconnects, and HDDs that require less power and advanced signal isolation. This serial transceiver is designed to support data-rates up to 10.3125 Gbps.

The VSC7281VT-03 has three transmitters, each of which uses an external voltage supply to generate an output signal. The power supply for each transmitter can be either 3.3V or 5V, depending upon the inputs, and the output voltage is programmed to be between -4V and 6V. Each channel of the VSC7281VT-03 also has its own control-signal conditioning circuitry to ensure isolation between the lanes. The control signals available include data-valid, reset, suspend and in/out-of-band hi/low, which provide an excellent level of control and monitoring. In addition, the VSC7281VT-03 transceivers feature an integrated EMI filter and a wide common-mode voltage range.

The VSC7281VT-03 transceivers use the Serial Lane Technology (SLT) protocol. This protocol allows each transmitter to identify the lane it is operating in and to switch lanes as needed, while using a common data clock. This ensures that data is sent out on the correct lane at the right speed, and it also reduces latency. The VSC7281VT-03 transceivers also use proprietary FIFO (First In First Out) technology that helps to minimize jitter and reduce latency. Furthermore, the VSC7281VT-03 allows for rate-adaptive data-signaling to accommodate varying transmission speeds.

The VSC7281VT-03 transceivers are also compatible with the Serial Attached SCSI (SAS) protocol, which is used in the majority of enterprise storage systems. The SAS protocol is designed to provide end-to-end communication between devices in the data path, allowing for more efficient data transfer and faster performance. Additionally, the VSC7281VT-03 transceivers are designed to be used in other serial storage systems, such as Fibre Channel, InfiniBand, and 10 Gigabit Ethernet.

In short, the VSC7281VT-03 transceiver is a versatile and reliable high-speed serial transceiver that is designed to meet the needs of numerous data-oriented applications. It is compatible with both the SAS and SLT protocols, and its integrated control-signal conditioning circuitry provides improved lane-to-lane isolation, low-power operation, and excellent performance. Its FIFO technology minimizes jitter and latency, and its integrated EMI filter offers superior protection against electromagnetic interference.
