The MD-015 is a Microchip GNSS disciplined atomic clock module. 1 PPS TTL, 10MHz sine wave, and 10 MHz square wave outputs are generated from an on-board low-power SA.65s Chip Scale Atomic Clock, a high-stability SA53, or a high-stability SA55 Miniature Atomic Clock which is disciplined to an embedded 72 channel multi-constellation GNSS receiver (with L1 L2 L5 upgrade options for dual-band multi-GNSS receiver supporting GPS, GLONASS, Galileo, and BeiDou) or an external reference input supporting input frequencies from 1Hz (1PPS) to 120 MHz.
