PLL: common questions

How big is the PLL PCB?

The PLL measures 50 × 200 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PLL?

78 components, from 32 distinct parts. The full bill of materials is listed on this page.

Where can I download the PLL design files?

From the telec16/modular-synth repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the PLL design in my own project?

The repository has no license, so all rights stay with telec16. Use it as a reference, and ask the author before reusing the design.
