THS788 4-Channel Timing Measurement Unit

Texas Instruments' 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 8 ps of single-shot accuracy. The TDC has 13 ps resolution (LSB), which is derived from an external master clock of 200 MHz. 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 200 MSPS. The 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).
