Hello! I was looking into purchasing an evaluation board for the Melexis Time-of-Flight Camera Chip MLX75027. There are a few questions about part identification that are not complete with the set or described in the product manual/specifications.
The evaluation boards have the following numbers:
1: EVK75027-110-940-2 ($3,125)
2: EVK75027-70-940-2-SLM ($3,360)
3: EVK75027-110-940-2-SLM ($3,360)
4: EVK75027-140-940-2-SLM ($3,360)

The following questions are:

  1. What does the product identifier 70, 110, and 140 mean in the manufacturers part number? What makes them different?
  2. Why are the prices different between the first and 2nd-4th products different?
  3. Each device is said to come with an Infrared filter attached to the camera? Do the eval kits come with this? Is it possible to get a kit with the board removed?
  4. What does SLM mean in the manufacturer product number?

Thank you for any insight!

Sorry for the long delay here is what we got back from the manufacturer ,

  1. What does the product identifier 70, 110, and 140 mean in the manufacturers part number? What makes them different?
    Answer: 70, 110, and 140 here mean horizontal field of view. Here is the convention how we define our EVK number: EVK(melexis product number) - horizontal field of view - wavelength - version - optional adder

  2. Why are the prices different between the first and 2nd-4th products different?
    Answer: Different versions can entail different hardware and thus different pricing.

  3. Each device is said to come with an Infrared filter attached to the camera? Do the eval kits come with this? Is it possible to get a kit with the board removed?
    Answer: All EVKs have IRBP mounted in sensor lenses. Customers can mechanically remove it, but Melexis is not liable for damage of any kind thereof. A safe way is to contact the lens supplier, Naotech, to request a lens version without IRBP integrated. For 110 degree FOV, please request NL1774 for QVGA resolution and NL3605 for VGA resolution, mentioning no IRBP 38nm filter.

  4. What does SLM mean in the manufacturer product number?
    Answer: SLM is an optional adder that identifies a specific illumination board design.

Hi Craig,
Thank you so much for getting back to me!
I do have a couple follow-up questions:

  1. Does the answer to the original question 3, imply that once the lens is taken off the sensor is not covered by anything?
  2. Does the EVK board have a way to access a 10MHz reference or synchronization signal used by the receiver? Or another question - does the EVK board have pins to access different signals on the PCBs?
