Domain index for in-vehicle networking PHYs and controllers: Classic CAN, CAN FD/SIC/SIC-XL, CAN XL PHY, isolated CAN, selective wake & partial networking, SBC with CAN/LIN, FlexRay PHY/controllers/star couplers, plus EMC co-design, protection, key specs, application patterns and design pitfalls.
CAN (incl. CAN FD / CAN SIC / CAN XL)
HS CAN Transceiver (ISO 11898-2)
1 Mbps classic CAN, short-to-VBAT/GND protection, wide common-mode tolerance, ±8–12 kV ESD, TxD dominant timeout and thermal shutdown.
CAN FD Transceiver (up to 2–8 Mbps)
Fast phase loop with symmetric loop delay and sample-point optimization; low emissions and strong RF immunity for higher bit rates.
Signal Improvement CAN (SIC / SIC-XL)
Improved signal integrity & symmetry for long harness/heavy loads, forward-compatible with CAN XL.
CAN XL PHY (~10 Mbps)
Triple-speed domain compatibility (Classic/FD/XL), higher host interface rates and emission-suppressed transmit stages.
Isolated CAN / CAN FD Transceiver
Reinforced isolation with high CMTI, optional isolated DC/DC; ideal where large ground potential differences exist (e-drive/HV domain).
Selective Wake / Partial Networking (ISO 11898-6)
Ultra-low standby with frame-filter wake, TC10 remote wake; enables power saving across body/comfort domains.
SBC with CAN FD
System basis chips integrating LDO/watchdog/wake management with CAN PHY (optional LIN), simplifying ECU power and networking.
CAN Controller / Bridge (incl. TTCAN)
Time-triggered messaging, filtering/remapping, and bridging to Ethernet/DoIP or automotive Ethernet gateways.
LIN (Local Interconnect Network)
LIN Transceiver (ISO 17987 / J2602)
Single-wire, wake/sleep modes, auto-baud detection and EMI-friendly slew-rate control.
LIN Master with HS Switch
Integrated pull-up/termination with high-side switch, over-current protection and hold-up features.
SBC integrating LIN
LIN + watchdog/reset + low-power policy in one SBC—ideal for numerous small ECUs in body/comfort domain.
FlexRay (ISO 17458)
FlexRay Transceiver (10 Mbps)
Dual-channel A/B, low jitter, bus/star topology compatibility with thermal and short-circuit protections.
FlexRay Controller
Time-triggered communication with static/dynamic segment scheduling, diagnostics and gateway functions.
Active Star Coupler / Repeater
Centralized star topology with fault isolation and redundant path management.
EMC / Protection & Co-Design
CMC & Split Termination for CAN/FlexRay
Suppress common-mode radiation and improve immunity; optimize midpoint-to-gnd capacitor/RC networks.
Port ESD/Surge Arrays (Low-C TVS)
Low-capacitance matched TVS arrays with IEC coupling models to avoid signal distortion.
Bus Diagnostics / Monitor IC
Open/short/over-voltage/balance detection with event counters and reporting.
EMC Hooks & Layout
Programmable slew/drive strength, standby current vs emission trade-offs, harness and star-ground planning.
Key Specs & Selection
Data Rate & Timing
Classic/FD/XL/FlexRay targets, loop-delay symmetry, sample-point and propagation-segment windows.
Robustness
Short-to-battery/ground survivability, ESD levels, common-mode range and CMTI (for isolated types).
Low-Power
Sleep Iq, selective-wake sensitivity/false-wake rate, and wake-source attribution (bus/local/timed).
Diagnostics & Safety
Fail-safe receive, bus fault detection, ASIL interface hooks and fault-injection support.
EMI Emission & Immunity
Programmable slew, SIC waveform integrity, harness/termination contributions to emissions.
Temperature & Aging
Automotive temp ranges, parameter drift, thermal shutdown and recovery strategies.
Application Patterns
Powertrain & Chassis ECUs
CAN FD/XL with isolated CAN across HV domains; FlexRay for chassis/steer-by-wire redundancy.
Body & Comfort
Large LIN node count with CAN-FD gateways; SBC-based low-power/wake management.
Diagnostics / Gateway / TCU
Multi-bus to Ethernet bridging, DoIP/OTA and secure gateway integration.
Sensors / Actuators Nodes
Compact LIN/CAN nodes with selective wake strategies to minimize quiescent current.
Design Hooks & Pitfalls
Termination & Cable Capacitance
Choose CAN/FlexRay end values and midpoint caps to avoid under/over-damping.
Stub & Harness Length
Keep stubs short and control T-branches—stricter for high-speed FD/XL networks.
Ground & Common-Mode
Plan ECU ground offsets and surge return; prefer isolation across HV domains.
Waveform & Sample-Point
Re-measure on real harness; adjust phase/propagation segments; ensure SIC/XL symmetry.
Wake/Sleep Strategy
Frame-filter tables, false-wake control and gateway timed wakes to avoid event loss.
Port Protection Parasitics
Low-C TVS/CMC and close placement to preserve edge rates and signal integrity.
Diagnostics & Logging
Error counters, bus utilization and wake-event black box for serviceability.
