Abracon introduced the AK2A/AK3A series with triple overtone technology ultra-low jitter quartz crystal oscillator

Abracon's latest ultra-low jitter clock series, the AK2A and AK3A, are designed to provide a stable and accurate clock signal for high-speed applications such as data centers, 100G/400G/800G Ethernet and optical modules. This series uses triple overtone technology to achieve jitter performance as low as 64fs and lower power consumption. As an extension of the ClearClock product family, they are ideal for applications with reference frequency ranges between 100 MHz and 212.5 MHz and channel rates up to 400 Gbps.

The AK2A and AK3A series are the perfect solution for compact design. This series of products is available in 2.5 mm x 2.0 mm and 3.2 mm x 2.5 mm packages, but has significantly improved jitter performance compared to the AK2 and AX3 series of the same size. This family of products supports multiple output logic types, such as LVPECL, LVDS, and HCSL. The product maintains ±25ppm frequency stability in the operating temperature range of -40°C to +85°C and ±15 ppm frequency stability in the operating temperature range of -20°C to +70°C.
