General Description

The MAX9424–MAX9427 high-speed, low-skew quad PECL-to-ECL translators are designed for high-speed data and clock driver applications. These devices feature an ultra-low 0.24ps(RMS) random jitter and channel-to channel skew is less than 90ps in asynchronous mode.

The four channels can be operated synchronously with an external clock, or in asynchronous mode determined by the state of the SEL input. An enable input provides the ability to force all the outputs to a differential low state.
