my customer needs an Ethernet multiplexer (see attachment). I found the TS3L501E but I'm not 100% sure if this IC fit. Siemens would like to switch between 100MbE (PHY 1) and 1GbE (PHY 2). The switch is connected to a RJ45 jack. The application is profinet. The 100MbE has 4 signals, 1GbE has 8 signals. The SEL signal is driven by a TTL signal.
Thanks a lot!
The TS3L501E Gigabit switch should be perfect for your application.
