Overview
The NB100LVEP222MNG is a low skew 2:1:15 differential div 1/div 2 ECL fanout buffer designed by onsemi, specifically tailored for high-performance clock distribution. This device is an improved version of the MC100LVE222, offering higher speed capability and reduced skew. It supports both LVECL and LVPECL input signal pairs, which can be used in differential or single-ended configurations. The device features four output banks that can be independently configured to fanout 1X or 1/2X of the input frequency, making it versatile for various clock distribution needs.

Q & A
- What is the primary function of the NB100LVEP222MNG? The NB100LVEP222MNG is a low skew 2:1:15 differential div 1/div 2 ECL fanout buffer designed for high-performance clock distribution.
- What input signal types does the NB100LVEP222MNG support? It supports both LVECL and LVPECL input signal pairs.
- How can the output banks be configured? Each of the four output banks can be independently configured to fanout 1X or 1/2X of the input frequency.
- What is the maximum frequency capability of the NB100LVEP222MNG? It can operate up to 1 GHz.
- What are the operating voltage ranges for LVPECL and NECL modes? For LVPECL mode, VCC = 2.375 V to 3.8 V with VEE = 0 V. For NECL mode, VCC = 0 V with VEE = -2.375 V to -3.8 V.
- What is the significance of the VBB output? The VBB output is used for rebiasing AC coupled inputs and as a switching reference voltage for single-ended LVPECL input conditions.
- How should unused output pairs be handled? Unused output pairs should be left unterminated (open) to reduce power and switching noise.
