TIME TO DIGITAL CONVERTERS
TDC-GPX2 High Performance Time-to-Digital Converter
The TDC-GPX2 is an upgraded version of the TDC-GPX. It is more powerful, has a lower cost and smaller package than the TDC-GPX. The TDC-GPX2 is an integrated four-channel Time-to-Digital converter offering single-measurement resolution of up to 20psRMS per channel in normal 4 channel mode. Operating in dual-channel high resolution mode, it can achieve a maximum resolution of 10psRMS with 5ns pulse-to-pulse spacing. The superior performance of the TDC-GPX2 has been achieved without sacrificing power efficiency. The GPX2 uses between 60mW and 450mW in normal operation depending on the number of channels and update rate, and draws just 60µA in stand-by mode.
Time to Digital Converters
The ScioSense TDC-GPX2 is easy to implement in end-product designs, providing standard interfaces and requires few external components. The chip also includes a driver for a quartz reference clock, which can be used for automatic calibration as an alternative to the reference clock input.
An evaluation kit is available for the TDC-GPX2, which includes a programmer and GUI software for PCs that enables customers to configure and connect their Start and Stop signals reducing the time to getting to taking sample time measurements.
ScioSense is already a leader in the LIDAR, laser scanner and 3D LIDAR market with the TDC-GPX for high precision ranging applications. The GPX2 provides even higher resolution, better precision and higher update rate that allow customers to develop systems with even higher detail and accuracy.
The TDC-GPX2 is a great upgrade from competitive technologies including the obsolete Texas Instruments (TI) THS789 Quad-Channel Time Measurement Unit (TMU).
TDC-GPX2 Applications
TDC-GPX2 LIDAR FOR AUTONOMOUS VEHICLES
Applications like LIDAR, laser scanning devices and 3D LIDAR used in autonomous vehicle applications require very high performance to acquire the data, process the data and
get it to the control system in sufficient time to make decisions for vehicle control and to avoid objects which have come into the vehicle’s path. The devices need to be small, light-weight and cost effective in order to be used in high volume applications.
The ability to measure short time intervals with high resolution and fast update rate enable LIDAR and laser scanning devices that are fast enough and accurate enough to be used in complex collision avoidance navigational systems found in autonomous drones, cars, robots and trucks. The GPX2 enables
systems to have more detailed data and very accurate range measurements.

TDC-GPX2 LIDAR FOR DRONES
Applications like LIDAR used in drone applications require very high performance to acquire the data, process the data and get it to the control system in sufficient time to make decisions for drone control so that the drone can avoid objects which have come into its path.
The devices need to be small, light-weight and cost effective to be used in high volume applications. In addition to collision avoidance, there are mapping applications that require laser scanners, which again must have high resolution, fast acquisition, and must be light-weight.
The TDC-GPX2 offers high resolution, 10ps, high update rate to the outside world (up to 70 mega-samples per second) using the low voltage differential signaling interface (LVDS), and it has very low power consumption in operation. All this performance is available in a small 9mm by 9mm QFN64 package. These features make it ideal for use in drones and it is already finding applications in this market segment today.

TDC-GPX2 TDC-GPX2 LIDAR FOR VIRTUAL REALITY APPLICATIONS
Applications like LIDAR and Laser Scanners used in virtual reality applications require very high performance to acquire the data, process the data and get it to the control system in sufficient time to make decisions of where you are in relation with objects in the environment so you can avoid objects which are in the way. The devices need to be small, light-weight and cost effective to be used in high volume applications. In addition to collision avoidance with the environment, the information can be used to map the room environment such that
the VR can take advantage of overlaying virtual objects over physical objects.
