SJA1105RELY Description

Short technical summary and product information.

The SJA1105RELY from NXP Semiconductors is a versatile 5-port Ethernet switch IC designed for high-performance networking applications. It supports a store-and-forward architecture with individual port configurability for 10/100 Mbit/s (MII/RMII) and 10/100/1000 Mbit/s (RGMII/SGMII) operation.

This device features independent I/O voltage domains, allowing selectable 1.8/2.5/3.3 V operation for various interfaces and a 1.2 V core voltage. It complies with IEEE 802.3 standards and offers advanced features like 4096 VLANs, priority-based QoS handling, and hardware support for IEEE 802.1AS timestamping and IEEE 802.1Qav AVB traffic shaping.

Packaged in a compact 159-LFBGA (12 mm x 12 mm) format, the SJA1105RELY operates within an ambient temperature range of -40°C to +105°C and is qualified according to AEC-Q100 Rev-H, making it suitable for demanding automotive environments. The SPI interface facilitates host processor access.

Key interface options include MII/RMII for Fast Ethernet, RGMII for Gigabit Ethernet, and SGMII for high-speed connections. Programmable drive strength is available for MII/RMII/RGMII interfaces. The device also includes features for cascading devices and synchronization.
