Frequency Prescalers and Dividers
Centellax is pleased to present the following prescaler and divider surface-mount packaged ICs and evaluation boards. These parts are broadband with excellent performance, and are easily integrated into your digital radio or custom synthesizer application. These dividers can also be used for high speed (Gb/s) signal processing applications like direct digital synthesis and numerically controlled oscillators.
Frequency Divider/Prescaler QFN Packages
Centellax offers a collection of dividers and prescalers in plastic quad, flat, no lead (QFN) lead-free packages. Each divider is fully programmable with multiple divide ratios, features differential inputs and outputs, and has excellent return loss and input sensitivity. Connectorized evaluation boards are available for each divider; click the divider name for more information.
