Applications
The SN74LV4046ADG4 is commonly used in clock synthesis, frequency multiplication, and frequency demodulation circuits in microcontroller-based systems, communication interfaces, and sensor signal conditioning boards. Its dual phase comparator design supports both lock-and-track and frequency sweep modes, making it suitable for FSK demodulators, tone decoders, and motor speed control feedback loops. It is also applied in data synchronization circuits for serial communication links and in clock recovery applications where a stable local oscillator must lock to an incoming data stream.

Frequently Asked Questions
What is the SN74LV4046ADG4 and what does it do?
The SN74LV4046ADG4 is a CMOS phase-locked loop (PLL) IC containing a voltage-controlled oscillator (VCO) and two phase comparators (PC1 and PC2). It locks an internal oscillator frequency and phase to an external reference signal, enabling frequency synthesis, clock multiplication, FM demodulation, and clock recovery in electronic circuits.
What supply voltage range does the SN74LV4046ADG4 support?
The SN74LV4046ADG4 operates over a supply voltage range of 2V to 5.5V, making it compatible with standard 3.3V and 5V CMOS logic systems. Its low-voltage capability also makes it suitable for 2.5V and battery-powered applications where power consumption and supply headroom are critical design considerations.
What is the difference between PC1 and PC2 phase comparators in the SN74LV4046ADG4?
PC1 is an XOR-type phase comparator that responds to both edges of the input and VCO signals, providing a 90-degree phase offset at lock. PC2 is a positive-edge-triggered phase-frequency detector that compares both frequency and phase, offering better lock range and eliminating false lock conditions — PC2 is preferred for most PLL applications requiring frequency acquisition.
What package does the SN74LV4046ADG4 use?
The SN74LV4046ADG4 is housed in a 16-pin Small Outline IC (SOIC) package with a 0.25-inch (6.35mm) lead pitch, designated by JESD-30 code R-PDSO-G16. This standard surface-mount package is widely supported by PCB design libraries and pick-and-place assembly equipment, with a peak reflow temperature rating of 260°C.
What are common applications for the SN74LV4046ADG4?
Common applications include frequency synthesizers, clock multipliers, FSK demodulators, motor speed control loops, tone decoders, and clock recovery circuits for serial data links. The SN74LV4046ADG4 is also used in frequency discriminators, voltage-to-frequency converters, and signal tracking filters in instrumentation and communication equipment.
