• Uses modern optical pumping instead of older magnetic cesium methods, which improves long-term stability and reliability while measuring many more atoms for highly accurate timing.
• Offers excellent frequency accuracy (≤ ±1×10⁻¹²) and very low phase noise on multiple frequency outputs (5 MHz, 10 MHz, 100 MHz), making it suitable for precise synchronization.
• Supports multiple power options (AC, DC ±24 V, DC −48 V) with redundant and hot-swappable supply modules and optional battery backup for one hour, aiding uptime in critical environments.

Brandywine Communication’s Have Quick/1PPS Distribution Amplifier (HQS) is a small rugged, powered Have Quick/1PPS distribution module mounted in a 4” x 4” x 2.5” environmentally secure enclosure. The HQS can provide an MTBF up to 1 million hours depending on configuration.

• First commercial high-performance cesium atomic clock using optical pumping — 100 times more atoms can be measured compared to magnetic clocks.
• Offers 10 times higher clock stability.
• Double the operational lifetime compared with traditional magnetic cesium clocks.
• Wide range of ultra-low noise frequency outputs (e.g. 5 MHz, 10 MHz, 100 MHz) — plus multiple 1PPS outputs, supporting high-precision timing distribution.
• Frequency accuracy ≤ ±5 × 10⁻¹³; reproducibility after power cycle ≤ ±1 × 10⁻¹³.
