AR8035 Integrated 10/100/1000 Mbps Ethernet
Transceiver
General Description
The AR8035 is part of the Arctic family of
devices - which includes the AR8031, AR8033,
and the AR8035. It is Atheros’ 4th generation,
single port 10/100/1000 Mbps Tri-speed
Ethernet PHY. It supports RGMII interface to
the MAC.™
The AR8035 provides a low power, low BOM
(Bill of Materials) cost solution for
comprehensive applications including
consumer, enterprise, carrier and home
networks such as PC, HDTV, Gaming
machines, Blue-ray players, IPTV STB, Media
Players, IP Cameras, NAS, Printers, Digital
Photo Frames, MoCA/Homeplug
(Powerline)/EoC/ adapters and Home Router
& Gateways, etc.
The AR8035 integrates Atheros latest Green
Ethos® power saving technologies and
significantly saves power not only during work
time, but also during overtime. Atheros Green
Ethos® power savings include ultra-low power
in cable unplugged mode or port power down
mode, and automatic optimized power saving
based on cable length. Furthermore, the
AR8035 supports Wake-on-LAN (WoL) feature
to be able to help manage and regulate total
system power requirements.
The AR8035 embeds CDT (Cable Diagnostics
Test) technology on-chip which allows
customers to measure cable length, detect the
cable status, and identify remote and local PHY
malfunctions, bad or marginal patch cord
segments or connectors. Some of the possible
problems that can be detected include opens,
shorts, cable impedance mismatch, bad
connectors, termination mismatch, and a bad
transformer.
The AR8035 also integrates a voltage regulator
on chip. It reduces the termination R/C
circuitry on both the MAC interface (RGMII)
and line side.
The AR8035 supports IEEE 802.3az Energy
Efficient Ethernet (EEE) standard and Atheros
proprietary SmartEEE, which allows legacy
MAC/SoC devices without 802.3az support to
function as the complete 802.3az system. The
key features supported by the device are:
n 10BASE-Te PHY supports reduced transmit
amplitude.
n 100BASE-TX and 1000BASE-T use Low
Power Idle (LPI) mode to turn off unused
analog and digital blocks to save power
while data traffic is in idle.
Features
n 10BASE-Te/100BASE-TX/1000 BASE-T
IEEE 802.3 compliant
n Supports 1000 BASE-T PCS and auto-
negotiation with next page support
n Supports RGMII interface to MAC devices
with a broad I/O voltage level options
including 2.5V, 1.8V and 1.5V, and is
compatible with 3.3V I/O
n RGMII timing modes support internal delay
and external delay on Rx path
n Error-free operation up to 140 meters of
CAT5 cable
n Supports Atheros latest Green Ethos®
power saving modes with internal
automatic DSP power saving scheme
n Supports 802.3az (Energy Efficient Ethernet)
n Fully integrated digital adaptive equalizers,
echo cancellers, and near end crosstalk
(NEXT) cancellers
n Supports Wake-on-LAN (WoL) to detect
magic packet and notify the sleeping system
to wake up
n A robust Cable Discharge Event (CDE)
tolerance of ± 6kV
n A robust surge protection with ±750V/
differential mode and ±4KV/common
mode
n Jumbo Frame support up to 10KB (full
duplex)
n All digital baseline wander correction
n Automatic channel swap (ACS)
n Automatic MDI/MDIX crossover
n Automatic polarity correction
n IEEE 802.3u compliant Auto-Negotiation
n Software programmable LED modes
n Multiple Loopback modes for diagnostics
