    Abstract: In an embodiment, a method includes: receiving a first plurality of digital codes from a TDC; generating a coarse histogram from the first plurality of digital codes; detecting a peak coarse bin from the plurality of coarse bins; after receiving the first plurality of digital codes, receiving a second plurality of digital codes from the TDC; and generating a fine histogram from the second plurality of digital codes based on the detected peak coarse bin, where a fine histogram depth range is narrower than a coarse histogram depth range, where a lower fine histogram depth is lower or equal to a lower coarse peak depth, and where a higher fine histogram depth is higher or equal to a higher coarse peak depth.

    Abstract: Disclosed herein is a time of flight sensing module that includes a reflected laser light detector formed on a printed circuit board, and a plurality of laser modules positioned about a periphery of the reflected laser light detector. Each laser module includes an interposer substrate vertically spaced apart from the printed circuit board, at least one laser diode carried by the interposer substrate, and a diffuser spaced apart from the interposer substrate and over the at least one laser diode. A lens may be positioned over the reflected laser light detector, and the plurality of laser modules are positioned about the periphery of the lens.

    Abstract: A time-of-flight ranging system disclosed herein includes a receiver asserting a photon received signal in response to detection of light that has reflected off a target and returned to the time-of-flight ranging system. A first latch circuit has first and second data inputs receiving a first pair of differential timing references, the first latch circuit latching data values at its first and second data inputs to first and second data outputs based upon assertion of the photon received signal. A first counter counts latching events of the first latch circuit during which the first data output is asserted, and a second counter counts latching events of the first latch circuit during which the second data output is asserted. Processing circuitry determines distance to the target based upon counted latching events output from the first and second counters.

    Abstract: A ToF sensor includes an array of pixels having first and second subsets of pixels, first and second pluralities of TDCs, a routing bus having first and second pluralities of bus drivers, and a controller configured to: when the first subset of pixels is active and the second subset of pixels is not active, control the first plurality of bus drivers to route events from half of the pixels of the first subset to the first plurality of TDCs and control the first and second pluralities of bus drivers to route events from the other half of the pixels of the first subset to the second plurality of TDCs, and when the first subset of pixels is not active and the second subset of pixels is active, control the first plurality of bus drivers to route events from the second subset of pixels to the first plurality of TDCs.

    Abstract: A depth map sensor includes a first array of first pixels, each first pixel having a first photodetector associated with a pixel circuit that comprises a plurality of first bins for accumulating events. A clock source is configured to generate a plurality of phase-shifted clock signals. A first circuit has a plurality of first output lines coupled to the first array of first pixels. The first circuit is configured to receive the plurality of phase-shifted clock signals. The first circuit includes a first block and a second block. The first block is configured to propagate the plurality of phase-shifted clock signals to the second block during a first period determined by a first enable signal and the second block configured to select to which of the plurality of first output lines each of the plurality of phase-shifted clock signals is applied.
