MC14046BCPG

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC14046BCPG is a Phase Locked Loop (PLL) integrated circuit manufactured by onsemi in a SOIC-16 Wide Body package. It integrates two phase comparators, a voltage-controlled oscillator (VCO), a source follower, and a zener diode. The device operates within a supply voltage range of 3.0 V to 18 V and supports an operating temperature range from -55°C to +125°C. Buffered outputs are compatible with Low-Power TTL logic levels. The component includes diode protection on all inputs and features a pin-for-pin replacement for the CD4046B.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the ordering suffix 'G' confirms the SOIC-16 WB package and Pb-Free status as specified in the datasheet. Confirm the specific revision level required for the design, as the document indicates Rev. 15. Ensure compatibility with existing PCB footprints for the SOIC-16 Wide Body outline before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a dual-phase comparator PLL is required for analog or digital signal processing. Phase Comparator 1 is suitable for duty-cycle-limited signals, while Phase Comparator 2 handles non-duty-cycle-limited inputs. Consider the 3 V to 18 V supply range and the -55°C to +125°C temperature rating for environmental constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The MC14046B series is a standard CMOS Phase Locked Loop designed for general-purpose frequency control applications. The MC14046BCPG variant specifically denotes the SOIC-16 Wide Body surface-mount package with lead-free construction. It serves as a direct functional equivalent to legacy CD4046B devices, allowing for straightforward upgrades in existing designs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The datasheet explicitly identifies the MC14046B as a pin-for-pin replacement for the CD4046B. Designers transitioning from other manufacturers should verify electrical parameter tolerances, particularly regarding input sensitivity and VCO linearity, against their original specifications.
