MOTOROLA SEMICONDUCTOR TECHNICAL DATA ÷2/4, ÷4/6 Clock MC100LVEL39 MC100EL39 Generation Chip The MC100LVEL39 is a low skew ÷2/4, ÷4/6 clock generation chip designed explicitly for low skew clock generation applications. The MC100EL39 is pin and functionally equivalent to the MC100LVEL39 but is specified for operation at the standard 100K ECL voltage supply. The internal dividers are synchronous to each other, therefore, the common output edges are all precisely aligned. The device can be driven by either a differential or single-ended LVECL or, if positive power supplies are used, LVPECL input signal. In addition, by using the VBB output, a sinusoidal source can be AC coupled into the device (see Interfacing section of the ECLinPS™ Data Book DL140/D).
