WHY AUTOMOTIVE ETHERNET ?

Source: BMW

► Higher data throughput is required for ADAS like rear view orsurround view camera systems

► Low latency is required for ADAS like for adaptive cruise control etc.

► Industry standards need to be integrated to save cost: 100BASE-T1 instead of MOST

► Reuse of TCP/IP in different application (flashing, camera, smart antennas) helps to reduce complexity

► Ethernet standards like Audio Video-Bridging, Time Sensitive Networks (TSN) enable new applications

► Unshielded Twisted Pair cabling to save cost

WHY MULTIGIG ETHERNET?

Important to know:

► Some automotive 4G LTE modems implemented in the

TCU can operate at 300-400 Mbps

Image source: Ficosa

ı T-Box 3.0: DA2300 will support 5G speeds up to 1.6Gbps*

*Maximum theoretical download speed

► TC9 UTP (Unshielded twisted pair) 1000BASE-T1, Final version 2.0 (Public)

Test of cable, connector and whole communication channel

4-Port Device needed: ZNB8, ZNB20, ZNB40

Differential return loss and insertion loss

Differential impedance (TDR)

Mode Conversion (-61 dB)

High VNA calibration accuracy required

SERDES DEBUGGING - JITTER AND EYE ANALYSISSERDES IS A FAST SERIAL INTERFACE

► Multitude of SERDES standards:

GSML (Maxim) up to 3.12Gbps

APIX up to 12 Gbps

…

► No dedicated TD or compliance needed –

they all require standard jitter and eye/mask testing

► RTP is best solution with realtime de-embedding, fast

update rate, CDR and advanced jitter capability
