TDC-GPX2 FLQM

Sensor And Detector Interfaces Overview

The ScioSense TDC-GPX2 FLQM is a four-channel time-to-digital converter housed in a QFP64 package. It operates on a 3.3V supply with an internal 1.8V core, supporting a reference clock frequency range of 2MHz to 12.5MHz. The device provides single-shot RMS resolutions of 20ps, 15ps, or 10ps depending on the high-resolution setting. Peak conversion rates reach up to 70MSPS when channels are combined, while maximum data throughput via LVDS outputs reaches 35.7MSPS per channel. It features a 4-wire SPI interface for configuration and supports pulse-to-pulse spacings as low as 5ns.

Sensor And Detector Interfaces Feature Summary

• Supports both CMOS and LVDS input/output levels for flexible system integration
• Includes automatic calibration to the reference clock without requiring PLL or DLL circuits
• Features four independent stop channels with 16-stage FIFO buffers per channel
• Provides configurable channel combining for enhanced pulse resolution or higher throughput

Sensor And Detector Interfaces Applications

• Automated test equipment
• Laser range measurement
• Medical imaging systems
• Time-of-flight measurements
• Particle physics experiments
• LiDAR, radar, and sonar applications

Sensor And Detector Interfaces Procurement Notes

Verify that the specific suffix FLQM corresponds to the QFP64 plastic package variant rather than the QFN64 option. Confirm the presence of RoHS compliance and lead-free matte tin finish requirements. Ensure the ordering quantity aligns with the manufacturer's standard factory packaging specifications for this package type.

Sensor And Detector Interfaces Selection Notes

Select the TDC-GPX2 FLQM when a QFP64 surface-mount package is required instead of the QFN64 alternative. Evaluate the need for LVDS interfaces versus CMOS inputs based on noise immunity requirements and power consumption constraints. Consider the 1.8V core voltage requirement alongside the 3.3V I/O supply for proper power domain design.

Sensor And Detector Interfaces Part Context

The TDC-GPX2 is part of the GPX series of time-to-digital converters manufactured by ScioSense. Originally developed under previous ownership entities including ams AG and acam-messelectronic GmbH, the technical specifications remain consistent across the lineage. This component serves as a high-performance frontend for precise time-interval measurements in digital acquisition systems.
