SINGLE-PORT BroadR-Reach™ AUTOMOTIVE ETHERNET
TRANSCEIVER
Overview
Highlights
• World's first automotive
BroadR-Reach physical layer
transceiver, supporting costeffective connectivity through
lower cabling and connector
cost.
• Advanced power savings with
Green technology.
• Highly optimized for multiple
in-car endpoint applications.
• Enhanced design to meet
stringent automotive production requirements.
• Supports various interface
options for connectivity to
external devices, making it the
perfect solution for in-car
applications such as camera
modules and RSE displays.
Product Family Features
The BCM89810 is a 100 Mbps automotive
Ethernet transceiver integrated into a single
monolithic CMOS chip. The device performs all
of the physical layer (PHY) functions for
BroadR-Reach™ encoded Ethernet packets
over single-pair unshielded twisted-pair copper wire, such as FlexRay™. The BCM89810 is
designed to exceed automotive specifications
for noise cancellation and transmission jitter,
providing consistent and reliable operation
over the broadest range of existing single-pair
twisted-pair automotive cable plants.
ments are utilized to increase design for
test, reliability, and quality to surpass AECQ100 and EMC requirements.
• Designed to support IEEE 1588 timing
function.
• Small size footprint support with 48-pin
MLP package.
• Automotive cable diagnostics feature can
detect pair open/short and distance.
Architectural Features
• Single BroadR-Reach transceiver in a fully
integrated 65 nm CMOS chip
• Full-duplex operation at the rate of
100 Mbps over one pair of UTP cable
• Fully integrated twisted-pair termination
resistors
• Trace-matched output impedance

BCM89810 Block Diagram
The BCM89810 is based on Broadcom's
proven digital-signal processor technology, combining digital adaptive equalizers, ADCs, phase-locked loops, line
drivers, encoders, decoders, echo cancelers, and all other required support circuitry. The BCM89810 is designed to be
fully compliant with RGMII and MII interface specifications, allowing compatibility
with industry-standard Ethernet media
access controllers (MACs) and switch controllers.
The device detects and corrects polarity
automatically. BroadR-Reach technology
enables the BCM89810 to auto-negotiate
and link up with BroadR-Reach compliant
link partners.
Ordering Information
