The GFT644 module is specially designed for interfacing high frequency clock and high speed
logic signal to multiple devices via long cable. All outputs with 50 Ω load can drive 100 feet of cable at clock rate greater than 150 MHz with 2.5 V amplitude.
The channel input threshold can be set to +1 or 0 or -1 V and the input load can be selected from
50 Ω or 1 KΩ pull up by a front panel switch. So that channel input can be driven directly by TTL
/CMOS logic levels or open collector or negative pulse (0 to -3 V) or AC coupled signal (± 0.5 V).
All outputs with 50 Ω load can drive 100 feet of cable at clock rate greater than 150 MHz with 2.5 V amplitude. Each output polarity can be set normal or inverted and outputs are compatible with DC or AC TTL input.
The GFT644 is a compact module supplied with a +5V AC/DC adapter
