Description

The TADD-3 Mini is a distribution amplifier for digital pulses. Its primary use is to distribute pulse-per-second (“PPS”) signals such as those obtained from GPS timing receivers. This version has SMA input and connectors.  The board has all surface mount components installed; the user must solder the input, output, and power connectors, and the option jumpers.

The TADD-3 Mini has 4 outputs with coax connectors as well as provision to install an LED.  Its input and outputs operate at either 3.3 or 5.0 volt logic levels, set by a jumper.  With 5 volts, it delivers greater than 3.5 volts into a 50 ohm load, with rise time of less than 3ns.

The SMA board is 2.5 x 3.0 inches (63.5 x 76.2 mm).  It requires a minimum DC input of about 5.5 volts (for 3.3 volt logic levels) or 7 volts (for 5 volt logic levels), and a maximum of 15 volts.  Power consumption without loads is less than 20 ma.

Two or more TADD-3 Minis of either or both types may be stacked to create 8 or more outputs from a single input.  Here are an SMA type stacked with a BNC type, and two BNC types stacked together:

TADD-3 Mini Combo
TADD-3 Mini SMA and BNC boards stacked
TADD-3 Mini Stacked BNC boards
TADD3-Mini Stacked BNC Boards

 

How is the TADD-3 Mini different from the original TADD-3?

  • 4 outputs instead of 8 (and no RS-232 outputs)
  • One input rather than two
  • SMA input connector
  • Input is logic gate only; no comparator option
  • Inverted 0utputs not available
  • 3.3 or 5V logic levels
  • Smaller
