DATA SHEET SKY53510/SKY53580/SKY53540 2. Detailed Description 2.1. Overview
The SKY53510/80/40 is a family of ultra-low additive jitter, low-skew, universal/any-format buffers. These devices can operate up to 3.1 GHz, featuring a 3:1 input multiplexer stage that can accept the most common differential or LVCMOS input signals. The output stage includes two banks of outputs, each of which includes pin-selectable output format selection and output supply voltage, as well as an LVCMOS reference output.
