Manufacturer:PANASONIC Description:The TSB17BA1 is a single-port 100-Mbps transceiver used in transporting IEEE Std 1394b (1394b) or other coded data across CAT5 or better cabling. It is attached to a 1394b-capable port on a 1394b physical layer (PHY) to enable 1394b 100-Mbps signals to be transmitted and received across up to 100 meters of unshielded twisted-pair category 5 (UTP5) cable. Equalization is applied to the signal received from the UTP5 cable to boost signal-to-noise ratio (SNR) to allow sensing of the data. A 1394b PHY device capable of transmitting at only 100 Mbits/s in 1394b-only mode is required for correct functionality. This PHY must be connected to the TSB17BA1 at one of the twisted-pair (TP) ports, with the 110-Ω 1394b transmission line properly terminated. The TSB17BA1 must then be connected to a 100-Ω transmission line properly terminated and connected to an isolating transformer. This transformer is then connected to an RJ45 connector. All of the parameters on the UTP5 side of the TSB17BA1 are set the same as 100baseT Ethernet. This allows the mechanical and magnetic infrastructure, which is used to design a 100baseT connection, to be used when designing a 100-Mbits/s UTP5 1394b connection. This device does not implement the autocrossover functionality described in chapter 12 of IEEE Std 1394b-2002. This means the required crossover of TPA to TPB and TPB to TPA must be done in the cable or connector or PWB; in other words, a mechanical crossover must be implemented (see the Application Information section). |
