AS6500: Time to Digital Converter (TDC)
The AS6500 is a high performance time-to-digital converter (TDC) frontend device. It is a derivative of the TDC-GPX2, with CMOS inputs and serial SPI output only. It comes in a QFN40 package.
High data throughput and measurement performance are attained by the AS6500 TDC. Numerous applications are covered by the high configuration flexibility and infinite measurement range, from high-performance time-of-flight measurements to small handheld laser rangefinders.
It computes stop measures that are calibrated and compared to the applied reference clock.
It is achievable to combine the lowest pulse-to-pulse spacing of <5 ns with a single shot precision of 10 ps and a maximum data input burst rate of 70 MSPS per stop input. SPI allows for a total data rate of roughly 1.5 MSPS.
FEATURES
- 2 stop channels with 5 ns / 20 ns pulse-to-pulse spacing.
- Maximum 70 MSPS per LVDS output.
- Single shot accuracy 20 ps RMS resolution per channel, 10 ps RMS with high resolution option.
- Unlimited measuring range 0s to 16s.
- Differential reference clock input 2 MHz to 12.5 MHz, optional with quartz.
- LVDS Inputs and outputs, 16-stage FIFO per channel, SPI compatible 4-wire interface for configuration, optionally to be used for data readout.
- Automatic calibration to reference clock.
- Supply voltage 3.3 V.
- Power dissipation up to 450 mW, standby current 60 μA.
- QFP48 package (7 x 7 mm², 9 × 9 mm² with leads).
BENEFITS
- Simple data post-processing thanks to calibrated results.
- Event assignment thanks to reference clock and index simplifies coincidence measurements.
- Easy pulse width measurements.
- High efficiency due to high sample rate.
- Compact design thanks to small package and low number of external components.
- Reduced cooling because of low power consumption.
