CD74HC4046AM96G4 - Phase-Locked Loop IC by Texas Instruments

The CD74HC4046AM96G4 is a high-speed silicon-gate CMOS Phase-Locked Loop (PLL) integrated circuit designed and manufactured by Texas Instruments. This versatile device is capable of performing a variety of functions including signal conditioning, frequency multiplication, frequency division, and frequency synthesis.

At the heart of the CD74HC4046AM96G4 lies a voltage-controlled oscillator (VCO), along with two different phase comparators (PC1 and PC2) with a common signal-input amplifier and a common comparator input. The VCO frequency is set with an external resistor and capacitor, and the device is capable of operating over a wide range of frequencies, from low to very high, depending on the choice of these external components.

The phase comparators have a common signal input and a common comparator input. The signal input can be directly coupled to large voltage signals, or indirectly coupled (with a series capacitor) to small voltage signals. A third comparator (PC3) is provided that is a simple exclusive OR logic gate. The CD74HC4046AM96G4 is well-suited for applications in FM modulation and demodulation, frequency synthesis and recovery, or wherever a reliable and precise phase-locked loop is required.

Key features of the CD74HC4046AM96G4 include:

• Wide supply voltage range from 2V to 6V
• High noise immunity characteristic of CMOS devices
• Low power consumption
• Linear voltage-controlled oscillator
• Wide range of VCO frequencies
• Minimal external components required

This integrated circuit is available in a 16-pin SOIC package, making it suitable for space-constrained applications. The CD74HC4046AM96G4 is a reliable choice for designers looking for a PLL with a high degree of versatility and performance. Its robustness and ease of use make it a popular choice for a wide array of electronic applications, from communications equipment to instrumentation and control systems.
