TJA1101 ETHERNET PHY TRANSCEIVER
The IEEE 802.3bw (100BASE-T1) compliant TJA1101
Ethernet PHY transceiver provides 100 Mbit/s transmit and
receive capability over unshielded twisted pair (UTP) cables
to withstand the most taxing automotive applications, while
still maintaining low-power consumption and system costs.
TJA1101 APPLICATION
The TJA1101 PHY transceiver provides robust, automotive-
grade signal quality with a bit error rate (BER) of at least
1E-10 or less. It is optimized for capacitive signal coupling
to the UTP lines and supports a cable length of at least 15
meters. To comply with automotive EMC requirements, a
common-mode choke (CMC) is typically inserted into the
signal path. Communication with the media access control
(MAC) unit can be realized via the MII or the RMII.
TJA1102 DUAL ETHERNET PHY TRANSCEIVER
The TJA1102, the industry’s
first 100BASE-T1 compliant
dual-port Ethernet PHY
transceiver, enables superior
system efficiency for high-
speed networks. This robust
and reliable transceiver offers
100 Mbit/s per port full
duplex and supports lightweight UTP cables of up to 30 m
in repeater mode for challenging automotive applications.
