TDC-GPX2 TRA

Sensor And Detector Interfaces Overview

The ScioSense TDC-GPX2 TRA is a four-channel time-to-digital converter housed in a QFN64 package. It supports LVDS stop inputs and serial outputs for maximum throughput, or CMOS inputs with SPI readout for power efficiency. The device achieves a single-shot accuracy of 10 ps RMS with high-resolution options and handles pulse-to-pulse spacing as low as 5 ns when channels are combined. Operating on a 3.3 V supply with an integrated 1.8 V regulator, it functions within a temperature range of -40°C to +125°C.

Sensor And Detector Interfaces Feature Summary

• Provides unlimited measurement range from 0 seconds to 16 seconds without locked-loop technologies
• Features automatic calibration proportional to the reference clock for simplified data processing
• Includes a 16-stage FIFO buffer per channel to manage high-speed event data

Sensor And Detector Interfaces Applications

• Laser range measurement systems
• Medical imaging applications requiring time-of-flight measurements
• Automated test equipment
• Particle physics experiments
• LiDAR, Radar, and Sonar signal acquisition

Sensor And Detector Interfaces Procurement Notes

Verify that the specific suffix 'TRA' corresponds to the QFN64 surface-mount package variant. Confirm the presence of RoHS compliance documentation for the final assembly. Ensure the ordering quantity matches the manufacturer's standard packaging specifications for this specific part number.

Sensor And Detector Interfaces Selection Notes

Select the TDC-GPX2 TRA when high data throughput via LVDS interfaces is required alongside compact board space constraints. This model is suitable for applications demanding sub-20 picosecond resolution and wide dynamic range timing capture. Evaluate power consumption requirements against the 60 mW to 450 mW dissipation range based on the chosen input/output configuration.

Sensor And Detector Interfaces Part Context

The TDC-GPX2 represents a high-performance member of the GPX family, designed for advanced time-of-flight sensing. It replaces legacy designs by offering superior measurement rates and data throughput. The component integrates multiple TDC cores into a single chip, eliminating the need for external locking loop circuits while maintaining precise temporal alignment across all channels.
