GNSS has become a critical component in autonomous and automotive vehicle applications, all of which require very high availability. As a result, resilient fault-tolerant components are essential to avoid service interruptions. Tallysman®’s TW162A is designed with AEC-Q100-certified components, ensuring the unit will operate under extreme temperature conditions.
The TW162A provides two key features:
First, it accepts power from all attached GNSS receivers and selects power from a receiver using the following protocol. Port #1 is given priority if its voltage is within the specified range (3.0 – 12.5 VDC). However, if port #1’s receiver is disconnected or if its receiver power goes below the under-voltage or above the over-voltage specification, the TW162A will switch to the next port in numerical order, as long as its power and voltage are within the expected range. The switching and port selection is, therefore, deterministic.
Second, if the antenna fails and does not draw current, the TW162A will provide all connectors with a current draw lower than 1 mA, indicating an antenna fault.
The TW162A offers the best-in-class performance in terms of noise figure, isolation, and linearity. In addition, it is packaged in a robust, compact, lightweight, and aluminum housing.
The TW162A is available with FAKRA connectors (3x Z or A+B+C) and offers standard gain to compensate for the signal-splitting loss.
