SY100EL34
Description
The SY10/100EL34/L are low-skew ÷2, ÷4, ÷8 clock generation chips designed explicitly for low-skew clock generation applications. The internal dividers are synchronous to each other; therefore, the mon output edges are all precisely aligned. The devices 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 ACcoupled into the device. 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/L under single-ended input conditions. As a result, this pin can only source/ sink up to 0.5m A of current.
The mon 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...
