SN74LV4046APWR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SN74LV4046APWR is a Phase Locked Loop (PLL) integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 5.5 V and features a maximum frequency of 38 MHz. The device is housed in a 16-TSSOP package with dimensions of 0.173 inches (4.40 mm) width. It supports CMOS and TTL input/output levels and functions across an operating temperature range of -40°C to +125°C. This single-circuit component is part of the 74LV series, designed for high-speed CMOS logic applications requiring precise frequency synthesis and clock recovery.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Integrates a Voltage-Controlled Oscillator (VCO) with a phase comparator for closed-loop frequency control.
• Supports both CMOS and TTL input logic levels for broad compatibility with standard digital interfaces.
• Provides a dedicated charge pump output to facilitate external loop filter design.

Clock Generators, PLLs, Frequency Synthesizers Applications

• Frequency synthesizers for communication systems
• Clock recovery circuits in data transmission links
• Motor speed control systems

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'PWR' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the operating temperature grade matches the application requirements, as industrial grades may differ from commercial variants. Cross-reference the manufacturer part number against current obsolescence notices to confirm availability.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a complete PLL solution including VCO and phase detector is required in a low-power CMOS process. Consider the 38 MHz maximum frequency limit relative to the target application bandwidth. Evaluate the 16-TSSOP package constraints for PCB layout space. Compare power consumption specifications against other members of the 74LV family if multiple logic functions are needed on the same board.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the SN74LV4046A series, which represents high-speed CMOS logic devices. The 'PWR' suffix specifically denotes the reel packaging format used for automated surface-mount assembly. It shares functional compatibility with the tube-packaged SN74LV4046APW variant, differing only in shipping configuration rather than electrical performance.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

SN74LV4046APW is a confirmed equivalent alternative offering identical electrical characteristics but supplied in tube packaging instead of tape-and-reel.
