onsemi MC100LVEP210: 2.5 V / 3.3 V 1:5 Dual Differential ECL/PECL/HSTL Clock Driver

The MC100LVEP210 is a low skew 1-to-5 dual differential driver, designed with clock distribution in mind. The ECL/PECL input signals can be either differential or single-ended if the VBB output is used. The signal is fanned out to 5 identical differential outputs. HSTL inputs can be used when the EP210 is operating in PECL mode.
