Overview

Preamp regulator is an open-source printed circuit board by nacs-lab, from the nacs-lab/yyc-data repository on GitHub. It is a 4-layer board of 56.4 × 61 mm with 90 parts on 26 nets, routed with 861 tracks and 79 vias.

It is built around the AD8429BR. Its parts include 50 capacitors, 24 resistors, 8 connectors and 6 ICs. It belongs with the power and audio and music boards of this library.

Orientations

Both connectors (Camera link an the 2x30 connector to the breakout board) and the decoder chip are on the same (front) side of the board, which is the side that is closer to the FMC connector and the DDS power supply connectors on the breakout board. Also the side that is farther from the FPGA board/chip.

When looking from the front side of the board with the 2x30 connector on the bottom and the camera link connector on the top, the PIN 1 of the 2x30 connector is on the bottom left of the board and it should be connected to the ground on the breakout board as well as all other odd number pins on this connector. Pin 60 of the connector is VCC3V3 from the FPGA board.

Camera link pin assignments

According to Andor's document, each pixel is a 16bit little endian integer, and according to the standard Port A and Port B should be used in this case.

Questions

How big is the Preamp regulator PCB?

It measures 56.4 × 61 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Preamp regulator use?

90 parts, built around the AD8429BR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Preamp regulator KiCad files?

From the nacs-lab/yyc-data repository on GitHub, at the commit this page was made from: the board is designs/combined_board/preamp_regulator.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Preamp regulator design in my own project?

Its repository states no licence, so its author keeps all rights: ask nacs-lab before reusing the design.
