NB100LVEP224FAR2

The NB100LVEP224FAR2 is a low skew 1-to-24 differential clock driver designed for clock distribution applications. It accepts two differential ECL/PECL clock sources and selects between them using the CLK_SEL pin. This device is suitable for low voltage applications requiring precisely aligned, low skew signals.

Key electrical specifications include a typical output-to-output skew of 20 ps and a device-to-device skew of 75 ps. The maximum operating frequency exceeds 1 GHz, with a typical propagation delay of 650 ps. It supports LVPECL mode with a VCC range of 2.375 V to 3.8 V (VEE = 0 V) and NECL mode with a VEE range of -2.375 V to -3.8 V (VCC = 0 V).

The NB100LVEP224FAR2 features internal input pulldown resistors. The Q output defaults to a low state when inputs are open or at VEE. The device is housed in a thermally enhanced 64-lead LQFP package, suitable for surface mounting.

This clock driver is designed for high-performance clock distribution in +3.3 V or +2.5 V systems. Unused output pairs should be left unterminated to minimize power and switching noise. Any unused single line of a differential pair should be terminated the same as the used line to maintain balanced loads.
