Product Overview
The AK3A is an ultra-low jitter, fixed-frequency SMD clock oscillator designed for high-performance applications. It offers exceptional RMS jitter of 83fs typ (LVDS @ 156.25MHz) and is available in industry-standard frequencies between 100MHz and 212.5MHz. With a 25ppm stability over an industrial operating temperature range of -40C to +85C, it provides reliable operation in demanding environments. The oscillator supports multiple differential output logic options including LVPECL, LVDS, and HCSL, and is available in a compact 3.2 x 2.5 x 1.0 mm footprint. Key applications include optical transceivers, data centers, networking switches, and industrial/FPGA applications.
