Overview

The NB100LVEP91 is a triple input to NECL output translator. The device accepts LVPECL, LVTTL, HSTL, CML or LVDS signals, and translates them to differential -2.5 V / -3.3 V NECL output signals.

To accomplish the level translation, the LVEP91 requires three power rails. The VCC supply should be connected to the positive supply, and the VEE pin should be connected to the negative power supply. The GNDI pins are connected to the system ground plane. Both VEE and VCC should be bypassed to ground via 0.01 uF capacitors.

Under open input conditions, the Dbar input will be biased at VCC/2 and the D input will be pulled to GND. This condition will force the Q output to a low, ensuring stability.

The VBB pin, an internally generated voltage supply, is available to this device only. For single-ended input conditions, the unused differential input is connected to VBB as a switching reference voltage. VBB may also rebias AC coupled inputs. When used, decouple VBB and VCC via a 0.01 uF capacitor and limit current sourcing or sinking to 0.5 mA. When not used, VBB should be left open.

  • Typical Maximum Frequency >2 GHz
  • 430 ps Typical Propagation Delay
  • Operating Range: VCC = 2.375 V to 3.8 V; VEE = -2.375 V to -3.8 V; GNDI = 0 V
  • Q Output will default LOW with Inputs Open or at GND
  • Pb-Free Packages are Available

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
