Low-Noise Chip-Scale Atomic Clock
The Low-Noise Chip-Scale Atomic Clock, model SA65-LN, enables frequency mixing for battery-powered devices
The Microchip SA65-LN is a second-generation Low-Noise Chip-Scale Atomic Clock (LN-CSAC) designed to meet the demanding requirements of aerospace and defense applications.
With its compact size, low power consumption, and high-precision capabilities, this innovative device offers unparalleled performance where traditional atomic clocks fall short. Ideal for environments where size, weight, and power (SWaP) constraints are critical, the LN-CSAC provides stable and precise timing in conditions where satellite-based systems may not be reliable.
Benefits:
Reliability: The LN-CSAC combines the reliability of a crystal oscillator and the precision of an atomic clock, ensuring consistent performance across a wide range of applications, from mobile radar to autonomous sensor networks.
Space and Power Savings: By integrating a crystal oscillator and atomic clock in one device, the SA65-LN helps save valuable board space and reduces design complexity while offering lower power consumption compared to separate oscillator designs.
Enhanced Durability: Its robust design is optimized for harsh environments and demanding applications, providing long-term stability without frequent recalibration.
Extended Mission Durations: With long intervals between calibrations, this clock ensures optimal performance during extended missions, reducing maintenance requirements and enhancing overall operational efficiency.
Key Features:
- Compact Design: At a reduced height of just ½ inch, the SA65-LN integrates Microchip’s proprietary Evacuated Miniature Crystal Oscillator (EMXO) technology, optimizing size without compromising performance.
- Low Power Consumption: Operating at less than 295 mW, the LN-CSAC is designed for power-sensitive applications, extending the life of mobile and unmanned systems.
- Wide Temperature Range: The device operates within a broad temperature range of −40°C to +80°C, ensuring stability and reliability even in extreme conditions.
- Low Phase Noise: With phase noise as low as −120 dBc/Hz at 10 Hz, the LN-CSAC ensures crystal-clear signal integrity and superior signal clarity.
- Atomic-Level Precision: Initial accuracy of ±0.5 ppb, frequency drift < 0.9 ppb/month, and temperature-induced errors of < ±0.3 ppb make it ideal for high-precision timing.
