SJA1105 Ethernet Switch Family
ETHERNET SWITCHES: ENABLING FASTER
IN-VEHICLE NETWORKS
The five-port automotive Gigabit Ethernet switch SJA1105x
series targets automotive applications such as gateway,
infotainment and ADAS fusion boxes with an array of
configurable ports, advanced security features and a
comprehensive, production-grade development ecosystem.
Each switch’s audio-video bridging support (AVB) feature
fully leverages infotainment and advanced driver assistance
systems.

ETHERNET SWITCH FAMILY
This Ethernet switch family extends the capability of the
previous SJA1105EL/TEL switches with improved security-
related features and extended interface options. The new
frame listing feature limits the switch data processing to known
sources, preventing the forwarding of erroneous or malicious
data. The updated interfaces offer extended IO voltage
supply options and a new SGMII interface. These interfaces
allow the switch to support any type of external PHY such as
Fast Ethernet, Gigabit Ethernet or 100BASE-T1 PHYs like the
TJA1101HN and TJA1102HN transceivers. The switch can also
operate as an inter-processor communication device between
multiple processors and the DSPs on the same board. All ports
can operate at gigabit speed in a non-blocking mode.
Finally, the switches are delivered with a rich set of tools,
including an evaluation board; original, production-grade
AUTOSAR drivers and AVB software stack.

SJA1105Q-EVB EVALUATION BOARD
The SJA1105Q-EVB is an evaluation system that supports
the SJA1105P/Q/R/S Automotive Ethernet switch family
together with the TJA1102HN Ethernet PHY. The board
enables the evaluation of the features common to the four
switch family variants and facilitates the early development
of the software required for the switch applications. Further
the board supports the OPEN Alliance TC10 Wake-up
Forwarding feature implemented by the TJA1102 dual
100BASE-T1 PHY. Finally, the board also offers a connector
capable of mating with NXP processor motherboards such
as i.MX 6, i.MX 8 and S32x processors families.
FEATURES:
• Enables evaluation of SJA1105P/Q/R/S series (with
exception of SGMII)
• Directly connect to PC via USB
• Connect to i.MX 6, i.MX 8 and S32x processor
evaluation boards
• Compatible with OPEN Alliance TC10 Wake
Up forwarding
• Software and documentation are available on docstore.
