MC12095DG

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC12095DG is a single modulus prescaler utilizing MOSAIC V technology for low power frequency division of high-frequency input signals up to 2.5 GHz. It operates on a supply voltage ranging from 2.7 V to 5.5 V with a typical current consumption of 8.7 mA. The device features an internal output termination capable of driving a 2.0 pF load and includes a divide ratio control input (SW) to select between ÷2 or ÷4 ratios. A Stand-By mode reduces current drain to approximately 100 µA when the SB pin is switched LOW. It is housed in a Pb-Free SOIC-8 package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering suffix 'DG' corresponds to the Pb-Free SOIC-8 package variant as specified in the manufacturer's ordering information table. Confirm that the procurement source provides documentation consistent with Publication Order Number MC12095/D. Ensure compliance with RoHS standards if required by the application environment.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component for applications requiring frequency division up to 2.5 GHz with minimal power consumption. The divide ratio is determined by the logic state of the SW pin, where HIGH selects ÷2 and OPEN selects ÷4. For designs requiring higher drive capability than the internal termination provides, an external resistor may be added in parallel from the OUT pin to GND, ensuring the maximum output current limit is not exceeded.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The MC12095DG belongs to the MC12095 series of low power prescalers manufactured by onsemi. It utilizes MOSAIC V technology to achieve performance at high frequencies while maintaining low power dissipation. The 'DG' suffix specifically denotes the Pb-Free version of the standard SOIC-8 package (Case 751), distinguishing it from non-Pb-Free variants like the MC12095D.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The MC12093 serves as a substitute for applications operating up to 1.1 GHz. Other available packages within the same functional family include the DFN8 (MC12095MNR4G) and tape-and-reel SOIC-8 (MC12095DR2G). Verify pin compatibility and thermal requirements when transitioning between package types.

Clock Generators, PLLs, Frequency Synthesizers FAQ

How is the divide ratio selected?

The divide ratio is controlled by the SW pin. Setting SW HIGH (VCC - 0.4 V to VCC) selects a divide-by-2 ratio, while leaving the SW pin OPEN selects a divide-by-4 ratio.

What is the function of the SB pin?

The SB pin controls the Stand-By mode. Switching SB LOW (GND to 0.8 V) disables the prescaler and reduces the supply current to approximately 100 µA.

Can the output drive capability be increased?

Yes. If additional drive is required beyond the internal termination, an external resistor can be added in parallel from the OUT pin to GND. Care must be taken not to exceed the maximum allowable output current of 8.0 mA.
