Microsemi CG1657 Daisy Chain Package

CG1657 Daisy Chain Package

Description
Microsemi’s Ceramic Column Grid Array (CCGA) daisy chain packages can facilitate the qualification of CCGA Field Programmable Gate Array (FPGA) board assembly practices without using flight-quality parts. These daisy chain packages have adjacent pairs of pins tied together. The daisy chain packages are then assembled onto a qualification PC board that is laid out with adjacent pairs of solder pads tied together but offset by one pin as compared to the daisy chain package, so that a single signal can be fed into one pin of the package and routed throughout the entire package. The routing is set in a serial daisy chain fashion such that almost all of the package pins are used.
Daisy chain packages can be used for performing continuity and impedance tests to validate board assembly techniques with surface-mount grid array packages. Microsemi’s daisy chain packages feature metal routing tracks between adjacent pairs of package pins, internal to the package.
The CG1657 Daisy Chain Package is a 1657-pin mechanical package of the CCGA type supporting the RTG4™ FPGA family.
