NOTE: The QLG2 module kits is currently out of stock, estimated availability is end-March 2021.

If you want your order to be split into two parts please make a separate order involving the QLG2 module kit http://shop.qrp-labs.com/qlg2

This kit is a simple minimalist controller for the Si5351A Synth kit (included with the ProgRock kit). It is intended as a programmable crystal replacement. It has three independent outputs with frequency range 3.5kHz to approx 300MHz, and can be optionally GPS disciplined by a GPS with 1pps output such as our QLG2 GPS receiver kit.

Kit features:

  • Includes Si5351A Synth kit and ProgRock PCB kit
  • Easy construction, no surface-mount components to solder (Si5351A already pre-soldered)
  • 3 independent 3.3V p-p squarewave outputs (2 if you use GPS discipline)
  • You can feed the output through our LPF kits to remove harmonics, to create sinewave outputs
  • 8 selectable “banks” of frequencies, chosen by 3 input control signals
  • Frequency range 3.5kHz to 200MHz
  • Extended frequency range up to approx. 300MHz if you don’t mind violating the Si5351A datasheet specifications
  • Quadrature output mode (Clk0 and Clk1 on same frequency but configurable 0, 90, 180 or 270-degree phase offset)
  • GPS frequency discipline using 1pps from a GPS receiver
  • Unique power supply noise filter circuit designed by Alan Gray G8LCO
  • Power supply voltage 5V, or using LM317LZ regulator (supplied), range is 5-12V DC
  • Minimalist configuration user interface using 4-way DIP switch, push button, and LED
  • Frequencies and configuration stored in non-volatilte memory (EEPROM) for next power-up
