A single Central Tracking Unit (CTU) chip can work with multiple sensors, each built from conventional low-cost PCB technology and used in conjunction with a simple target. This delivers a particularly cost effective solution for such multi-axis systems.
Centralising the position processing in a CTU chip also means that there is a single source of position feedback for the host, rather than the network of connections required for a traditional multi-axis system.
The number of sensors supported by a CTU chip depends on the CTU and sensor type. For example, the CAM204 CTU chip supports 4 Type 1 sensors. This number may be extended further with additional multiplexing circuitry. Please contact CambridgeIC for details.
