  • ONET1101L: The input and output waveforms of onet1101L do not match

    Part Number: ONET1101L Tool/software: Hello, when using onet1101L, I found that the output pulse width is much wider than the input pulse width, and the width of the output pulse width is more than twice the width of the input pulse width; The input frequency…

  • ONET1101L: ONET1101L Input Signal Frequency Issue

    TI Thinks Resolved
    Part Number: ONET1101L Tool/software: hello： May I ask If the input frequency is several hundred megahertz, but the single pulse width is less than 500ps, does it also meet the chip's usage conditions？ We look forward to your reply！

  • ONET1101L: Why hasn't there been a response regarding the case of ”The input and output waveforms of onet1101L do not match“?

    Part Number: ONET1101L Tool/software: The last reply was on January 31, 2025. Since then, there has been no response from my forum replies or private messages. I hope someone can continue to handle this case and provide me with a clear way to contact…

  • ONET1101L: The additional power consumption issue caused by impedance matching of onet1101L

    TI Thinks Resolved
    Part Number: ONET1101L Tool/software: onet1101L,The chip output is stated on the datasheet as having a 25 ohm impedance, which means that an impedance matching network needs to be used for impedance matching in the output section. After reviewing the…

  • ONET1101L: Differential output impedance matching scheme

    Part Number: ONET1101L Tool/software: There is a differential connection between R86 and LD_CTHODE, and the PCB layout is shown in the figure, where R85 is actually short circuited. The current phenomenon is that R86 welds a 49.9R resistor with…

  • ONET1101L: Laser safety feature

    Part Number: ONET1101L Tool/software: We are using Onet1101L for modulation of laser diode with a built-in photo detector. Our circuit design is more or less a copy of the reference design in the data sheet. We operate in APC mode with a bias current…

  • ONET1101L: Laser diode driver ic required

    Part Number: ONET1101L Can you suggest any laser diode driver IC which can be used for drive 1550nm wavelength with 10Nsec pulse width for fiber optical transmitter

  • ONET1101L: Laser CW mode of operation settings

    TI Thinks Resolved
    Part Number: ONET1101L Other Parts Discussed in Thread: ONET1151L Tool/software: Hi, We have a laser which we want to drive with ONET1101L in Continuous wave (CW) mode. How do I make the modulation 0? Is it right to connect them to the ground? IS…

  • ONET1101L: How to connect the chip input signal DIN+ / DIN

    TI Thinks Resolved
    Part Number: ONET1101L Hello， I want to use the ONET1101L chip to drive the laser diode. In the process of looking at the datasheet, I saw that the input terminal DIN+ and DIN- are forward input terminal and reverse input terminal respectively. I want…
