Master Clock Reference PCI Card

Our master clock reference (MCR) card is a PCI card that provides stable accurate time and date information for a Windows PC. The card uses a Real Time Clock (RTC) chip and oscillator with temperature compensation to stabilize the PC clock. The MCRPCI maintains PC accuracy to 165 ms/day, or 1 minute per year. The on-board clock runs from a backup battery in the absence of power from the PC.
