Power microchip MAC-SA5X

The MAC-SA5X is designed for applications that require rubidium atomic clock holdover performance but are constrained by size and low power requirements. Its superb short-term stability (Allan Deviation), resistance to temperature changes (tempco) and long-term drift performance allow tight synchronization to GNSS timing or another primary reference clock. This enables nanosecond holdover performance for days at a time. Key Features The MAC-SA55 offers excellent stability for its size: < 1.5E-11 ADEV @ 1s < 5E–11 monthly aging (frequency drift per month) < 5E–11 frequency change vs. −40°C to +75°C temperature change < 200 ns holdover ability over 24 hours (typical, static temperature) Remote monitoring and control (RS232 and USB) 1 PPS disciplining from externally supplied signal (phase and frequency calibration) Dimensions: 51 × 51 × 18 mm
