Overview
The MC12093 is a single modulus prescaler designed for low power frequency division of high frequency input signals up to 1.1 GHz. Utilizing MOSAIC V™ technology, this component achieves low power dissipation of 6.75 mW at a minimum supply voltage of 2.7 V. It features on-chip output termination to drive high impedance loads and includes a stand-by mode to reduce current drain to 50 μA typical when the prescaler is disabled.
