TDC-GP1

Sensor And Detector Interfaces Overview

The TDC-GP1 is a general-purpose Time-to-Digital Converter manufactured by acam-messelectronic gmbh. It provides two measurement channels with 250 ps resolution or one channel with 125 ps resolution in High Resolution Mode. The device supports two measurement ranges: Range 1 covers 3 ns to 7.6 µs, while Range 2 extends up to 200 ms using a predivider. It features an internal 16-bit ALU for calibration and multiplication, four ports for R-L-C measurements, and a standard 8-bit microcontroller interface. Operating voltage ranges from 2.7 V to 5.5 V within an industrial temperature range of -40 °C to +85 °C.

Sensor And Detector Interfaces Feature Summary

• Dual-channel architecture with identical resolution or single-channel high-resolution mode
• Internal arithmetic logic unit for real-time calibration and data processing
• Software-adjustable resolution via Resolution Adjust Mode for quartz-accurate stability
• Integrated R-L-C measurement capabilities for sensor applications

Sensor And Detector Interfaces Applications

• Precision time interval measurement
• Phase difference detection of phase-modulated signals
• Resistor, inductor, and capacitor sensing via ratio measurements
• Multihit event recording with queuing capabilities

Sensor And Detector Interfaces Procurement Notes

Verify the manufacturer designation as acam-messelectronic gmbh rather than ScioSense, as the provided datasheet explicitly identifies the source. Confirm package compatibility with the 44-TQFP form factor and ensure supply chain documentation aligns with the specific component revision. Cross-reference ordering codes against official acam documentation to avoid substitution errors.

Sensor And Detector Interfaces Selection Notes

Select the TDC-GP1 when sub-nanosecond timing precision is required for time interval conversion. Choose the dual-channel mode for independent stop measurements or the High Resolution Mode for 125 ps precision. Utilize the Resolution Adjust Mode if long-term stability without separate calibration is necessary. Ensure the application fits within the specified voltage and temperature operating limits.

Sensor And Detector Interfaces Part Context

The TDC-GP1 belongs to the family of digital propagation time-based converters developed by acam-messelectronic gmbh. It utilizes CMOS technology to achieve resolutions between 30 ps and 300 ps. The device is designed for high-precision applications where traditional meters lack sufficient expenditure or accuracy, serving as a specialized analog-to-digital converter for temporal data.

Sensor And Detector Interfaces Replacement Considerations

No public substitute part numbers are documented in the provided material. The TDC-GP1 is a proprietary design by acam-messelectronic gmbh. Any replacement must be evaluated based on functional equivalence regarding resolution, interface standards, and measurement range specifications.

Sensor And Detector Interfaces FAQ

How does the Resolution Adjust Mode affect power consumption?

In Resolution Adjust Mode, the unit consumes approximately 25 mA regardless of the measuring rate, which significantly limits battery operation compared to normal modes.

What is the double pulse resolution limit?

The double pulse resolution is approximately 15 ns. If two stops arrive on the same channel within less than 15 ns, the second stop is ignored due to the recovery time of the measurement unit.

Can the TDC-GP1 measure negative time differences?

Yes, the device can identify and measure negative phase situations or time differences, allowing for direct measurement of phase modulation around zero without needing to know which event occurred first.
