Introduction

Abracon's AK2A/AK3A is an ultra-low RMS jitter oscillator designed to provide stable and accurate clock signals for high-speed applications such as data centers, 100G/400G/800G Ethernet, and optical modules. This device uses third overtone technology to achieve 64fs jitter performance and lower power consumption. As an extension of our ClearClock® line, it is ideal for applications that require a carrier frequency between 100 and 212.5 MHz and need lane rates to 400Gbps. The AK2A/AK3A is the perfect solution for compact designs as it still supports industry-standard footprints of 2.5 x 2.0 mm and 3.2 x 2.5 mm, but substantially improves the jitter performance over the AK2 and AX3 family. These series of oscillators are available in Abracon's global distribution network and offer various output logics like LVPECL, LVDS, and HCSL. While still delivering reliable and efficient oscillations, these devices can maintain a 25ppm stability over a temperature operating range of -40°C to +85°C and 15ppm stability over -20°C to +70°C.

Features

Third Overtone Architecture

• Provides a quieter technology that avoids phase locked loop (PLL) based multiplication which can significantly reduce overall power consumption.

Low Power Consumption

• Supports compact applications such as optical modules, active cables, or battery-operated system, where power consumption is a critical factor.

Compact Size

• Saves valuable board space and allows for flexible layout designs. This is important for compact applications where space is limited.

High Data Rates

• Can maintain data rates up to 100G/400G/800Gbps to enable reliable and accurate clock signals.

Supports Various Differential Outputs

• Allows our ClearClock® devices to be easily integrated into a wide range of systems, making it a versatile solution.
