Overview
The MC12093DR2, manufactured by onsemi, 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 device achieves low power dissipation, making it suitable for applications requiring efficient power management. The prescaler supports divide ratios of ÷2, ÷4, or ÷8, controlled by the SW1 and SW2 pins. It also features a Stand-By mode that reduces current drain to 50 µA typical when the standby pin SB is switched LOW, disabling the prescaler.
