Time Measurement Unit (TMU)

Quad Channel Time Measurement Unit

Texas Instruments

The THS788 is a four-channel timing measurement unit (TMU) that incorporates a time-to-digital converter (TDC) architecture for fast and accurate measurements.

Product Description

The THS788 is a four-channel timing measurement unit (TMU) that incorporates a time-to-digital converter (TDC) architecture for fast and accurate measurements. The TMU is able to provide 8ps of single-shot accuracy. The TDC has 13ps resolution (LSB), which is derived from an external master clock of 200MHz. It uses fast LVDS-compatible interfaces for all of its event inputs and serial result outputs, which allows for fast and reliable data transfer. Each channel can process time stamps at a maximum speed of 200MSPS.
