MC10EP139, MC100EP139
3.3 V / 5 V ECL ÷2/4, ÷4/5/6 Clock Generation Chip
Description The MC10/100EP139 is a low skew ÷2/4, ÷4/5/6 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 common enable (EN) is synchronous so that the internal dividers will only be enabled/disabled when the internal clock is already in the LOW state. This avoids any chance of generating a runt clock pulse on the internal clock when the device is enabled/disabled as can happen with an asynchronous control.
