Acting as interface between the physical bus layer and the CAN protocol controller, the IFX1051 drives the signals to the bus and protects the microcontroller against interferences generated within the network. Based on the high symmetry Data Sheet 1 Rev. 1.0 www.infineon.com/transceivers 2017-03-15 IFX1051 Industrial High Speed CAN-FD Transceiver Overview of the CANH and CANL signals, the IFX1051 provides a very low level of electromagnetic emission (EME) within a wide frequency range. The IFX1051 is available in a small, leadless PG-TSON-8 package as well as in a standard PG-DSO-8 package. The packages are RoHS compliant and halogen free and moreover support the solder joint requirements for automated optical inspection (AOI). The IFX1051 is fulfilling or exceeding the requirements of the ISO11898-2. The IFX1051 provides a digital supply input V that allows direct interfacing to 3.3 V microcontrollers and in IO addition offers a Receive-only mode. One key feature of the IFX1051 is that it fulfills the enhanced physical layer requirements for CAN FD (CAN with Flexible Data Rate) and supports data rates up to 2 MBit/s. This allows the usage of the IFX1051 in networks using CAN FD protocol next to all industrial CAN applications using the classical protocol. CAN FD based networks offer a considerably increased bandwidth compared to classical CAN protocol because it allows increased data bitrate in combination with increased payload per message and thus making CANFD a powerful and future-oriented alternative for all existing CAN applications whenever bandwidth limitations become an issue. On the basis of a very low leakage current on the HS CAN bus interface the IFX1051 provides an excellent passive behavior in power-down state. These and other features make the IFX1051 exceptionally suitable for mixed supply HS CAN networks. In addition the IFX1051 provides excellent ESD immunity together with a very high electromagnetic immunity (EMI). Moreover the IFX1051 is equipped with a TxD time-out functionality which protects the CAN bus from being blocked if the transceiver receives by error a permanent low level signal on TxD from its controller. The implementation of this functionality with a very long delay timing of > 4.5 ms allows at the same time the usage of the device in physically very long bus networks as they can be found in many industrial applications. The two different operating modes - Normal mode and Receive-only mode, its additional fail-safe features like TxD time-out but as well the CAN FD capability and optimized output slew rates on the CANH and CANL signals make the IFX1051 an ideal choice for large HS CAN networks with demand for high data transmission rates.
