74HC4046APW,118

Clock Generators, PLLs, Frequency Synthesizers Overview

The Nexperia 74HC4046APW,118 is a high-speed Si-gate CMOS phase-locked loop (PLL) circuit housed in a TSSOP16 package. It integrates a linear Voltage Controlled Oscillator (VCO) and three selectable phase comparators: an EXCLUSIVE-OR network (PC1), an edge-triggered J-K flip-flop (PC2), and an edge-triggered RS flip-flop (PC3). The device operates with a VCO supply voltage range of 3.0 V to 6.0 V and a digital section range of 2.0 V to 6.0 V. It features a typical center frequency of 17 MHz at 4.5 V, low standby power consumption via VCO-inhibit control, and excellent VCO linearity.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the component against the official Nexperia datasheet Rev. 7 specifications. Confirm the ordering suffix matches the required TSSOP16 package variant. Ensure compliance with JEDEC standards and RoHS directives during acceptance testing. Validate pinout alignment with SOT403-1 mechanical drawings before integration into the PCB layout.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single-chip PLL solution with multiple comparator types is required. The HC technology ensures compatibility with standard CMOS logic levels. Consider the specific phase comparator needs; PC2 offers full capture range independence from filter characteristics, while PC1 provides noise immunity. Verify that the operating voltage aligns with the 3.0 V to 6.0 V VCO supply requirement.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the 74HC4046A family of phase-locked loops manufactured by Nexperia. It is functionally compatible with the 74HCT4046A series, though input level specifications may differ slightly. The APW suffix specifically denotes the plastic thin shrink small outline package (TSSOP16), distinguishing it from the SO16 variant.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Public confirmed substitute part numbers include 74HC4046AD,653 and 74HC4046AD,652. These alternatives share the same functional block diagram but utilize different packaging formats such as SO16. Verify package dimensions and pin compatibility before substitution.
