MC12026ADR2

The MC12026ADR2 from On Semiconductor is a high-frequency, low-voltage dual modulus prescaler suitable for phase-locked loop (PLL) applications. This device can be integrated with CMOS synthesizers that require positive edges to trigger internal counters, providing tuning signals up to 1.1 GHz in programmable frequency steps.

A key feature is the Divide Ratio Control (SW), which allows selection between an 8/9 or 16/17 divide ratio. The Modulus Control (MC) then selects the appropriate divide number. The prescaler operates with a supply voltage range of 4.5V to 5.5V and has a typical supply current of 4.0 mA.

Designed for reliability, the MC12026ADR2 has an operating temperature range of -40°C to 85°C. It comes in a compact 8-SOIC package, suitable for surface mount applications. The device also features a short setup time of 6.0 ns typical at 1.1 GHz and is compatible with standard CMOS and TTL logic levels for its Modulus Control input.

This component is Pb-Free, Halogen Free, and RoHS Compliant, making it suitable for environmentally conscious designs. Its pin compatibility with the MC12022 further adds to its utility in existing designs.
