MC100EL34

MOTOROLA SEMICONDUCTOR TECHNICAL DATA ÷2, ÷4, ÷8 Clock Generation Chip The MC10/100EL34 is a low skew ÷2, ÷4, ÷8 clock generation chip designed explicitly for low skew clock generation applications. 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 ECL or, if positive power supplies are used, PECL 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). If a single-ended input is to be used, the VBB output should be connected to the CLK input and bypassed to ground via a 0.01µF capacitor. The VBB output is designed to act as the switching reference for the input of the EL34 under single-ended input conditions, as a result, this pin can only source/sink up to 0.5mA of current. The common enable (EN) is synchronous so that the internal divi...
