- Datasheet


The GFT614 module is specially designed for distribution of high frequency clock and high speed logic signal to multiple device via long cable. All outputs with 50 Ω load can drive 100 feet of cable at clock rate greater than 200 MHz with 2.5 V amplitude.

The input load can be selected from 50 Ω to 1 KΩ by a front panel switch.

The channel input can be driven directly by TTL logic levels. The output is compatible with DC or AC TTL input.

A gate input allows to disable the module by external signal.

The GFT614 is a compact module supplied with a +5V AC/DC adapter

Typical GFT614 application would be to distribute High speed signal to four devices via long cable (up to 100 feet).
