TW162A

TW162A Automotive-Grade 1-to-2 Port Smart Power GNSS Signal Splitter

Frequency Coverage: Full GNSS Spectrum

Overview

The Tallysman® TW162A is an automotive-grade full GNSS band Smart

Power signal splitter that connects one antenna to two receivers, and
supports GPS/QZSS-L1/L2/L5, QZSS-L6, GLONASS-G1/G2/G3, BeiDou-
B1/B2/B2a/B3, Galileo-E1/E5a/E5b/E6, NavIC-L5, and L-Band correction
services.

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.
