SJA1105PELY

The SJA1105PELY from NXP Semiconductors is an advanced Ethernet switch IC designed for high-performance networking applications. It features a 5-port store-and-forward architecture, with each port individually configurable for speeds up to 1000 Mbit/s via MII/RMII, RGMII, or SGMII interfaces.

This device supports independent I/O voltage domains (1.8/2.5/3.3 V) and a 1.2 V core voltage. It adheres to 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. It also includes 16 credit-based shapers for flexible traffic management.

Packaged in a compact LFBGA159 (12 mm × 12 mm) footprint, the SJA1105PELY operates within an Automotive Grade 2 ambient temperature range of -40 °C to +105 °C. Its qualification in accordance with AEC-Q100 Rev-H ensures reliability in automotive environments. The IC also features a SPI interface for host processor access and supports JTAG for testing.

Key interface options include MII/RMII for Fast Ethernet, RGMII for Gigabit Ethernet, and SGMII for high-speed connections. The device also provides a 25 MHz system clock input and output, along with synchronization outputs for cascading devices.
