LTDC-X3 is a high-performance 2-channel time-to-digital converter specifically designed for single-beam LIDAR systems.
It has a separate START channel, measures up to 4 pulses on rising and/or falling edges, has a pulse-paire resolution as low as 5 ns, a typical rms resolution of 20ps and a range up to 2.4 µs. It integrates a start pulse generator for trigger signals to an external laser diode driver.
Equipped with a quad SPI interface the data rate can be as high as 50MHz / 200MBPS.
It comes in a QFN32 package and works in the industrial temperature range.
