BASE backplane -- 4-slot short
version
The BASE boards plug into two types of backplanes -- 4-slot or 10-slot versions.
The 4-slot version has one clock driver pcb, one signal processing pcb, a dsp pcb, and a power pcb. It is a 2-channel design, useful for a system with one or two ccds.
The 10-slot version has four clock driver pcbs, four signal processing pcbs, a dsp pcb, and a power pcb. It is designed to be used with an 8-channel mosaic ccd array.
Each backplane slot has a 120-pin DIN connector, with 0.1 inch pin spacing. The pcbs are four layers, with buried ground plane and power layer.
