This is a “production” version of my 1PPS distribution prototype. Now, this device supports 1PPS and Square clock signal distribution for 8 consumers. The new device is designed with lower delays and flexible configuration in mind. You can find the schematic and all required production files below.

1PPS distribution circuit
1PPS is a great way to synchronize multiple devices and measure time intervals. A typical source of the 1PPS is a GPS receiver. This clock is disciplined by GPS atomic clock and has a reasonable precision. GPS receiver 1PPS output should have enough loading capability, but it’s a good idea to use a buffer. Especially when voltage level translation is…
Combining two HackRF SDR to see more
HackRF One is a popular SDR transceiver and a really nice piece of hardware. For a reasonable price, you can get fully open hardware to monitor radio signals in a wide range (20MHz – 6GHz, but really up to 7GHz). Boards support external clocking and can be easily customized. I believe there is only one concern about this board is…
