Overview
The MC12026ADR2G is a high-frequency, low-voltage dual modulus prescaler developed by onsemi. This component is designed for use in phase-locked loop (PLL) applications, particularly with CMOS synthesizers that require positive or negative edges to trigger internal counters. It is capable of providing tuning signals up to 1.1 GHz in programmable frequency steps.
The device features a dual modulus prescaler with divide ratios of 8/9 or 16/17, selectable via the Divide Ratio Control (SW) and Modulus Control (MC) inputs. It operates within a supply voltage range of 4.5 to 5.5 volts and has a low typical supply current of 4.0 mA. The MC12026ADR2G is packaged in an SOIC-8 surface mount package and is RoHS compliant, making it suitable for a wide range of modern electronic designs.
