Texas Instruments THS788 Quad Channel
Time Measurement Unit
Texas Instruments THS788 Quad-Channel Time Measurement Unit (TMU) incorporates a time-to-digital converter (TDC) architecture for fast and accurate measurements. The TMU can provide 8ps of single-shot accuracy. The TDC has 13ps resolution (LSB), which is derived from an external master clock of 200MHz. The TI THS788 Quad-Channel TMU uses fast LVDS-compatible interfaces for all of its event inputs and serial result outputs, allowing for fast and reliable data transfer. Each channel can process time stamps at a maximum speed of 200 MSPS. The TI THS788 has a wide range of programmability that makes it flexible in different applications. The serial-result interface has programmable data length, frequency, and data-rate mode (DDR and normal). The event channels can be programmed to take time stamps on rising edges or falling edges. The TMU includes a mode for event management that allows the user to program wait times before measurements. The TI THS788 is ideal for use in a variety of applications, including automatic test equipment, benchtop time-measurement equipment, radar and sonar, medical imaging, and more.
