SP3494CN-L

SP3494CN-L is a fully integrated, ultra-low power, single-ended driver, receiver, and transceiver designed for gigabit Ethernet and IEEE1394 applications. Its high performance, low power operation, small footprint, and low cost make it ideal for use in embedded systems, optical networking applications, and industrial equipment.

Application Field

The SP3494CN-L is a high performance, single ended driver, receiver, and transceiver ideal for 1Gbps and Gigabit Ethernet applications. It supports the 10Base-T, 100Base-T, 1000Base-T, and 1000Base-X Ethernet standards, and is fully compliant with the IEEE1394.1, IEEE1394b, and IEEE1394c protocols. It is also suitable for numerous other applications such as fiber optic communication systems, embedded systems, digital cameras/recorders, telecommunication systems, and automotive systems.

Working Principle

The SP3494CN-L is an integrated single-ended driver, receiver, and transceiver that operates using differential signaling. It features an internal analog-to-digital converter (ADC), digital-to-analog converter (DAC), and a high-efficiency dielectric field-effect transistor (EFET) for low-power operation. The integrated EFET in the SP3494CN-L reduces power consumption and provides higher signal-to-noise ratio (SNR) and better signal integrity than traditional ESD protection devices. The device operates on a single 3.3V supply and has a maximum data throughput of 1000MB/s. It supports half-duplex and full-duplex operation modes, and can be used in optical links and copper based network topologies.

The SP3494CN-L uses inductors and capacitors to achieve signal termination and signal conditioning, as well as an on-board EMI filter to reduce EMI noise. Additionally, the device includes a built-in Temperature Monitor (TMON) to provide real-time monitoring of the device\'s temperature. This feature helps to ensure reliable operation and helps to prevent overheating.

The SP3494CN-L is equipped with an internal self-test function that can automatically verify the functionality of the device at power-up and during regular operation. In addition, the onboard First-in-First-out (FIFO) can be used by the host controller to provide buffering of received and transmitted data packets.

The SP3494CN-L is an excellent choice for high-speed Gigabit Ethernet and IEEE1394 applications due to its high performance, low power consumption, small footprint, and low cost.
