FX-700-EAE-KNKN-A5-EA

Specialized Overview

The FX-700-EAE-KNKN-A5-EA is a crystal-based frequency translator designed for communications applications requiring low jitter. It operates on a 3.3V or 5.0V supply and features a tri-state output to facilitate board testing. The device translates frequencies up to 77.760 MHz and is capable of locking to an 8 kHz pulse or BITS clock. It utilizes advanced custom ASIC technology for robust performance. The component is housed in a hermetically sealed 16-pad ceramic SMD package measuring 5.0 x 7.5 mm with a maximum height of 2.13 mm. It supports commercial and industrial temperature ranges from -40 °C to +85 °C.
