The feature list in the data sheet says this device is rated for 400Mbps operation, but Figure 17 (transmission distance vs. rate) indicates that it can't operate anywhere near 400Mbps at at distance. In fact at 10m the rate is limited to between 4-5Mbps…
Hi Bill,
The TX/RX pairs should not be tied together. The stub created by this as well as additional loading from the TX/RX can cause signal integrity issues. If you have a half-duplex application you should use the SN65LVDM176 instead. But yes hot plugging…
1) Propagation delay requirements for cable certification are the same for all twisted pairs
2) The device was characterized with a 15 pF load. It will probably be higher at higher capacitive loads but we cannot quantify it
3) The device was characterized…
Part Number: SN65MLVD040 Other Parts Discussed in Thread: SN65LVDM176 , SN65MLVD206B Hello, I'm trying to get some guidance on a design I'm working on. Right now I have a Xilinx FPGA driving some LVDS GPIO out of a backplane, to an I/O card, and out the…
Other Parts Discussed in Thread: SN65LVDM176 , DS91D176 , SN55LVDS31 , SN55LVDS32 hello, let's say I wanted to create a 2-wire multipoint LVDS bus. Rather than selecting a dedicated half-duplex device such as the SN65LVDM176 or DS91D176, where the transmitter…
Lee,
This has been observed with devices such as SN65LVDM176. if 2 devices are active (driving) at the same time, then both devices will be damaged. This has been seen in a multipoint configuration.
what I meant for full-duplex was a multidrop configuration…
