The Microchip/TrueTime 560-5217 is an AC/DC power supply module integrated within the TrueTime 56000 series Data Rate Clock and Distribution System. This modular chassis platform delivers precision frequency references, clock distribution, and timing outputs for telecommunications and industrial synchronization networks. The power supply supports the system’s hot-swappable architecture and enables operation of multiple synthesizer, distributor, and timing reference cards across 16 available slots.
