While experimenting with my clock distribution amplifier, I found that this board creates a lot of interference to my HackRF receivers. Plus, it’s not very convenient to work with a bare board. I decided to build metal housing for this board. This is just a little note about its construction and some nuances.
1PPS/Square clock 8 channel distribution amplifier
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…
