TDC-GP22 TRA

Sensor And Detector Interfaces Overview

The TDC-GP22 TRA is a Time-to-Digital Converter (TDC) module manufactured by ams OSRAM. It is designed for high-precision time measurement applications, particularly in LiDAR and distance sensing systems. The device converts the time interval between a start signal and a stop signal into a digital value with picosecond-level resolution. Key electrical parameters include a typical time resolution of 50 ps, a maximum input frequency of 10 MHz for both start and stop channels, and an operating voltage range of 3.0 V to 3.6 V. The module features a serial peripheral interface (SPI) for configuration and data readout, supporting multiple measurement modes including single-shot and continuous averaging.

Sensor And Detector Interfaces Procurement Notes

Verify the exact part number suffix, as 'TRA' may indicate specific packaging or tape-and-reel configurations. Confirm RoHS compliance and lead times with authorized distributors. Ensure compatibility with your system's voltage levels and SPI protocol settings before ordering.

Sensor And Detector Interfaces Selection Notes

Select this component when picosecond-level time resolution is required for distance measurement. Consider the 10 MHz input frequency limit for high-speed applications. Verify that the 3.0 V to 3.6 V supply range matches your power design. Compare with other TDC solutions if lower cost or different interface options are needed.

Sensor And Detector Interfaces Part Context

The TDC-GP22 is part of ams OSRAM's portfolio of precision timing and sensing solutions. It complements their laser diodes and photodiodes, such as the SFH series, forming complete LiDAR subsystems. The TRA variant likely refers to a specific reel or tape configuration for automated assembly.

Sensor And Detector Interfaces Replacement Considerations

No direct public substitute part numbers are confirmed for the TDC-GP22 TRA. Alternative TDC chips from other manufacturers may require significant circuit redesign due to differences in resolution, interface, and pinout.
