MC145152DW2R2

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC145152DW2R2 is a CMOS phase-locked loop (PLL) frequency synthesizer designed for parallel input programming with dual-modulus prescalers. It integrates a reference oscillator, selectable-reference divider, digital phase detector, and counters. The device operates on a 3.0 V to 9.0 V supply and supports an operating temperature range of -40°C to 85°C. Key features include a lock detect signal, user-selectable ÷ R values, and enhanced transfer function linearity via a linearized digital phase detector. It interfaces directly with dual-modulus prescalers for high-frequency applications.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the SOG package designation (Case 751F) and the specific suffix 'DW2R2' against current manufacturer documentation to confirm availability and exact ordering specifications. Ensure compatibility with external dual-modulus prescalers for system integration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when interfacing with dual-modulus prescalers is required for frequency synthesis. Compare against the MC145151-2 if single-modulus prescaler support is sufficient, as the MC145152-2 offers extended programmability for higher frequency ranges through its dual-modulus counter structure.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the MC145151-2/MC145152-2 family of PLL frequency synthesizers manufactured by Freescale Semiconductor (now NXP). The MC145152 variant specifically addresses applications requiring dual-modulus prescaler interfaces, distinguishing it from the single-modulus MC145151 series within the same functional block diagram lineage.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The MC145152-1 is the predecessor model. The MC145152-2 serves as an improved-performance drop-in replacement with decreased power consumption and enhanced ESD and latch-up protection capabilities while maintaining pin compatibility.
