MC12026ADR2

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC12026ADR2G is a high-frequency, low-voltage dual modulus prescaler designed for phase-locked loop (PLL) applications. It operates with a supply voltage range of 4.5 V to 5.5 V and supports toggle frequencies up to 1.1 GHz. The device features a typical supply current of 4.0 mA and an operating temperature range from -40°C to +85°C. It provides programmable divide ratios of 8/9 or 16/17 via Divide Ratio Control (SW) and Modulus Control (MC) inputs. The output voltage swing ranges from 1.0 Vpp to 1.6 Vpp depending on load conditions.
