TJA1102SHN/0Z - Single-Port 100BASE-T1 PHY | NXP
MPN: TJA1102SHN/0Z ✓ AktifTJA1102SHN/0Z Genel Bakış
A 100BASE-T1 Ethernet PHY is an integrated physical-layer transceiver that converts digital data into automotive Ethernet signals and receives signals from the opposite end of the twisted pair. It sits within the Ethernet communications hierarchy, where the PHY supports the physical signaling layer beneath a network stack. In vehicle networks, this technology supports bandwidth-efficient connections for vehicle-to-vehicle communication, gateways, IP cameras, driver-assistance systems, and backbone networks.
The TJA1102SHN/0Z provides a 100 Mbit/s data rate, single-port configuration, and IEEE 100BASE-T1 compliance. Its automotive-oriented integration is intended to reduce the external filtering and ESD-protection requirements associated with the medium dependent interface path. The device also supports OPEN Alliance TC-10 compliant sleep and wake-up forwarding over the data line, allowing a dormant link to be awakened without a separate dedicated wake-up conductor.
The TJA1102 family combines a highly integrated Ethernet physical layer with automotive interface functions. The SHN/0Z order code is supplied in a 56-terminal HVQFN package with 56 terminals and an 8 x 8 mm outline. The exposed-pad construction supports thermal transfer through the PCB, although exact junction-temperature limits, supply-voltage ranges, transceiver timing limits, and pin definitions must be confirmed in the manufacturer datasheet before release.
Typical applications include automotive Ethernet gateways, IP camera links, driver-assistance systems, vehicle backbones, and other in-vehicle networks that require 100BASE-T1 connectivity over a single twisted pair. In these systems, the PHY replaces a longer multi-pair Ethernet cable architecture with one compact data link while retaining a 100 Mbit/s line rate.
For PCB implementation, preserve the pin assignments, exposed-pad connection, decoupling configuration, high-speed differential routing, and controlled-impedance geometry shown in the NXP datasheet. The automotive cable interface should also follow NXP's recommended termination, protection, and connector integration, and the board should be validated for EMC, ESD, vibration, and temperature requirements applicable to the vehicle platform.
This page combines the exact ordering information, automotive Ethernet use cases, interface characteristics, package details, and drop-in-family guidance needed to evaluate the TJA1102SHN/0Z before schematic capture and PCB layout.

Tipik Uygulamalar
TJA1102SHN/0Z için uygundur 6 uygulamas: Automotive Ethernet Gateway, Automotive IP Camera Link, Driver Assistance Network, Vehicle Backbone Ethernet, Vehicle-to-Vehicle Communication, Automotive Power and Sensor Nodes.
Automotive Ethernet Gateway
The TJA1102SHN/0Z is suitable for an automotive Ethernet gateway that connects vehicle domains over a compact in-vehicle network. Its single IEEE 100BASE-T1 channel provides 100 Mbit/s transmit and receive capability over one unshielded twisted pair, reducing cable bulk compared with a multi-pair arrangement. OPEN Alliance TC-10 compliant sleep and wake-up forwarding over the data line can also reduce wiring requirements in a compatible gateway design. The engineer should retain the NXP reference network and verify EMC, ESD, impedance, and vehicle-level power-disturbance performance during integration.
Önerilen
Automotive IP Camera Link
The TJA1102SHN/0Z can provide a 100 Mbit/s Ethernet path for an in-vehicle camera or IP camera node using a single twisted pair. Its 100BASE-T1 interface supports links up to at least 15 m, which is useful for camera positions distributed through a vehicle. The integrated automotive-oriented MDI path can reduce external filtering and ESD-protection component count compared with a less integrated implementation. Design work should follow the NXP cable-side termination and protection guidance and validate image-transfer integrity under conducted noise, vibration, and temperature variation.
Önerilen
Driver Assistance Network
The TJA1102SHN/0Z fits a driver-assistance network node requiring a compact, reliable 100BASE-T1 link. A 100 Mbit/s channel over one twisted pair can connect a sensing or control node without the conductor count of conventional multi-pair Ethernet. The part is identified as an AEC-Q100 automotive device, while its OPEN Alliance TC-10 sleep and wake-up forwarding supports compatible low-power network architectures. Integration must still address functional safety partitioning, diagnostic behavior, EMC immunity, and fault containment at the vehicle system level.
Önerilen
Vehicle Backbone Ethernet
The TJA1102SHN/0Z can be used as a single-port node on an automotive Ethernet backbone carrying 100 Mbit/s over an unshielded twisted pair. Its ability to support cable runs up to at least 15 m helps accommodate in-vehicle harness distances while limiting wiring complexity. The exposed-pad HVQFN construction also requires a PCB thermal strategy that promotes reliable operation across the vehicle temperature range. For backbone deployment, engineers should confirm topology support, wake-up behavior, diagnostic coverage, cable qualification, and EMC performance against the applicable vehicle program.
Önerilen
Vehicle-to-Vehicle Communication
The TJA1102SHN/0Z is applicable to vehicle-to-vehicle communication nodes that need an automotive Ethernet physical layer for exchanging data over a twisted pair. Its 100 Mbit/s operation provides sufficient throughput for moderate control and sensing traffic while allowing a smaller, lighter harness than conventional Ethernet alternatives. Because communication reliability depends on the complete physical implementation, the PCB should follow NXP's reference layout and cable interface guidance. System validation should include EMC emissions, transient immunity, ESD performance, wake-up behavior, and link operation across temperature and vibration extremes.
Önerilen
Automotive Power and Sensor Nodes
The TJA1102SHN/0Z can connect a distributed automotive power or sensor node to an Ethernet backbone where a 100 Mbit/s single-pair link is sufficient. Its integration and single-port structure simplify modules that need one network connection rather than two independent PHYs. OPEN Alliance TC-10 sleep and wake-up forwarding can help low-power nodes wake through the data line in networks designed for that feature. The module designer should budget decoupling according to the datasheet, provide thermal relief for the exposed pad, and verify the cable and connector assembly against vehicle EMC requirements.

Tasarım Notları
Route the 100BASE-T1 cable-side differential pair as a controlled-impedance pair and follow the NXP reference layout without adding unnecessary stubs, vias, or test-point discontinuities. Keep the PHY-side connection and connector interface geometry consistent with the manufacturer's cable and connector guidance. Correct impedance and symmetry are particularly important because the single twisted-pair interface must maintain reliable data recovery under automotive EMC conditions.
The 56-terminal HVQFN includes a bottom thermal pad that should be connected according to the NXP land-pattern and solder-mask guidance. Use an array of thermal vias where space permits and avoid interrupting high-speed return-current paths. Thermal performance depends on the exposed-pad copper area, via count, board thickness, surrounding components, enclosure, and ambient temperature, so validate the final assembly rather than relying on package dimensions alone.
Place all required bypass capacitors close to their associated supply and ground pins, with short and low-inductance connections. Keep the supply-return path continuous beneath the device and separate noisy switching or high-current paths from the PHY interface area. Review startup, current limits, power-save transitions, and wake-up sequencing in the datasheet before assigning system power states.
Do not assume that every TJA1102 order code is interchangeable: the family includes single-port and dual-port versions, and suffix-specific options can differ in qualification, temperature grade, or interface behavior. Use the complete pin-description table and ordering information to confirm the physical package and exposed pad. Substituting the dual-port TJA1102 for this single-port design is not a drop-in replacement.
