Best Choice
The BCM8950X family of products are the optimal
solution for key automotive designs that have highperformance yet challenging low-power requirements. Building upon industry-leading 65 nm architecture, the BCM8950X family of products supports
multiple intuitive low-power modes as well as an
automotive cable diagnostics feature.
Architectural Features
• Enhanced architecture supports nonblocking,
line-rate data transfer at wirespeed performance for all fame sizes over unshielded single-pair twisted cable.
• Integrated switch core has provisions for the
integrated ARM® Cortex™ R4 processor and
dedicated on-chip SRAM to send and receive
frames.
• Processor subsystem able to support timing
stack and AVB bridging support functions.
• Support for Deep Sleep and Ultra Low Power
modes, which reduce power consumption to
zero during periods of inactivity.
Product Family Features
• Specific architectural and design enhancements are utilized to increase design for test,
reliability, and quality to surpass AEC-Q100
and EMC requirements.
• Designed to support IEEE 1588 and IEEE
802.1AS timing functions.
• Designed to support both peer-to-peer and
end-to-end transparent clocking in hardware.
• Automotive cable diagnostics feature can
detect pair open/short and distance.

BCM89501 Block Diagram
The BCM8950X family expands Broadcom’s leadership in Ethernet switching
technology by delivering an optimized
solution for automotive applications
requiring nonblocking switching performance
Examples of applications requiring nonblocking switching include multiview
advanced driver assist systems, where
multiple cameras are connected to a
switch in the electronic control unit
(ECU), or an infotainment network,
where numerous multimedia endpoints
are connected to a head unit.
The BCM8950X product family can interconnect with other devices for scalable,
high-performance systems through multiple interfaces including RGMII, GMII, MII,
and Turbo MII.
Requirements such as high-precision stereo cameras, rear-seat entertainment
units, and multichannel amplifiers are
driving the need for adherence to quality
of service requirements, specifically
highly synchronized and accurate timing.
