Miniature rubidium clock Micro rubidium clock, chip level atomic clock quote

Product Description:

The SA.3xm is the smallest commercially available rubidium atomic clock in the industry, offering numerous advantages such as low power consumption and compatibility with standard oven-controlled crystal oscillator (OCXO) footprints. With a compact size of only 50mm x 50mm, users can easily upgrade their existing boards that currently use crystal oscillators to a rubidium atomic oscillator without considering pinouts and dimensions. Its exceptional aging rate, low power consumption, and high accuracy make it ideal for synchronization and timing applications in telecommunications networks, testing and measurement equipment, and power and communication instruments.

The SA.3xm series of rubidium clocks represents a significant advancement in rubidium atomic clock technology. Based on next-generation atomic clock technology, the SA.3xm features a new physical micro-package along with outstanding performance characteristics such as aging rate, low power consumption, high accuracy, and wide temperature range. It fully meets the synchronization and timing requirements in telecommunications networks, testing and measurement equipment.

This product is suitable for various communication applications, including remote unmanned base stations or mobile base stations for CDMA, WCDMA, TD-SCDMA, as well as demanding fields like DVB or WiMAX. It is applicable to a wide range of telecommunications and transmission applications.

Key Features:

● High-precision atomic clock

● Micro packaging (51*51mm), smaller than most OCXO sizes

● Standard quartz oscillator output pins

● Low power consumption

● Independent free-run stable frequency source (suitable for UMTS or LTE)

● Long-term holdover capability for CDMA and WiMAX base stations

● Stability meets the requirements of various communication and transmission applications.
