Hi All,
My name is SK Lee. I'm in charge of DFAE in WTK. WTK is one of distributor in South Korea.
I have a question for 10BASE-T1L PHY Chip. (Part # : ADIN1100)
(Background)
- As we know, ADI have some experience for communication distance depending on the cable spec.
- Cable Spec : BELDEN / 74040NH / 1-Pair / Solid Core / 18AWG / Impedance 100ohm / 1,500m
- Cable Spec : BELDEN / 3076F / 1-Pair / Stranded / 18AWG 7/26 / Impedance 100ohm / 535m
- We are using 2 EA of the EVAL-ADIN1100 boards as below and have established a 600 meters using ethernet cable using CAT.5 AWG 24 reliable cable.
- We are using the GUI tool supported in ADI website. (Ethernet PHY Evaluation Version : 1.8.100.5320)
- Test Result : Link Up and Packet Test OK
- So far, OK
- Now We are trying to establish a link using traditional 1-Pair Cable of customer, But we couldn’t make a link establishment. The cable spec we are using as below picture.
- Style : UL 2464
- AWG Size : 18AWG (34/33AWG) Stranded
- 1-Pair (without twisted)
- Isolation resistance : 15Mohm
- Impedance : unknown
- Test Result : Link Down (Link Failed)
- EVAL-ADIN1100 : 2.4V peak to peak mode
(Question)
- How can we make a link establishment using above 1-pair cable ?
- Are there any modification parameter in GUI tool as below display ?
- Are there any cable specification we should check ? Impedance ?
