ISL31470EIBZ-T Application Field and Working Principle

The ISL31470EIBZ Series Tiny 10GbE to PMA/PMD Interface Transceiver (ISL31470EIBZ) is a low-power transceiver designed for backplane and chip-to-chip interconnects applications requiring data rates up to 10Gbps. The ISL31470EIBZ is the industry\'s first solution to feature a built-in PMA/PMD interface, providing a single-chip, low-power solution for 10GbE applications. The ISL31470EIBZ is designed to operate dramatically over a wide temperature range (-40°C to +85°C) and is ideal for datacenter, telecom, enterprise and computing applications.

The ISL31470EIBZ provides a simplified system interface to the PMA/PMD layer. It accepts a 10GbE data stream on a single differential pair and provides access to the media interface and optional forward error correction (FEC) functions. The transceiver supports both XFI and XAUI interfaces. The integrated PMA/PMD provides a direct link to 10G Ethernet media such as copper cables, optical modules, and active optical cables (AOCs).

The ISL31470EIBZ includes an integrated, low-power media access controller (MAC) that supports multiple media types and data rates, including 10,100,1000, and 10Gbps. The integrated MAC can support SGMII, RGMII, 10/100/1000 Ethernet or 10G Ethernet via XFI/XAUI. The ISL31470EIBZ also supports PCIe and USB 2.0 and 3.0 interfaces for improved system connectivity.

The transceiver is compatible with most leading Ethernet switches, media conversion solutions and edge-to-edge fabric solutions. Additionally, the ISL31470EIBZ supports the IEEE 802.3 (10GBASE-T) and 802.3ab (1000BASE-T) standards, making it an ideal solution for providing high-speed, low-power performance in today\'s demanding networking environments.

Working Principle

The working principle of the ISL31470EIBZ transceiver is based on a modulation and demodulation process. The 10Gbps data is first modulated at the transmitter using a modulation scheme such as 8B/10B or 64B/66B. The modulated data is then passed through the drivers, which amplify the signal for transmission. At the receiver, the signal is demodulated, and the data is recovered. The data is then passed to the PMA/PMD layer for further processing.

The transceiver includes integrated lane equalization and coding/decoding circuitry to optimize the signal performance. It also includes built-in error correction and phase-interleaving capabilities to improve the data integrity. The low power consumption of the ISL31470EIBZ allows it to work effectively in both high-speed and low-power environments.

The ISL31470EIBZ features an integrated energy detector that detects incoming signal energy and the receiver\'s own energy. With the energy detector, the transceiver can adjust its power consumption based on the incoming signal level. This helps conserve power and minimize system cooling requirements.

Conclusion

The ISL31470EIBZ series Tiny 10GbE to PMA/PMD Interface Transceiver is a low-power, single-chip transceiver designed for backplane and chip-to-chip interconnects applications that require data rates up to 10Gbps. The transceiver supports XFI and XAUI interfaces and is compatible with most leading Ethernet switches, media conversion solutions, and edge-to-edge fabric solutions. It also features an integrated energy detector that helps conserve power and minimize system cooling requirements. The ISL31470EIBZ is an ideal choice for datacenter, telecom, enterprise, and computing applications.
