Product Details

The CD4046BPW is part of TI's 4000 series of CMOS logic integrated circuits. It features low power consumption and a wide range of operating voltages, making it suitable for battery-powered devices and other low-power applications. The device comes in a TSSOP-16 (Thin Shrink Small Outline Package) which offers a reduced footprint on PCBs (Printed Circuit Boards) compared to other package types.

This PLL device includes a voltage-controlled oscillator (VCO), two different phase comparators, a zener diode for VCO control voltage input, and a source follower as an output for the VCO. The phase comparators have a common signal-input amplifier and a common comparator input. The first comparator provides a frequency and phase comparison, while the second offers a narrow pulse when the input signals are in phase, which is useful for lock detection.

The CD4046BPW is capable of operating over a wide temperature range, thus ensuring reliability across various environmental conditions. Its frequency range extends up to 18MHz, providing flexibility for a broad spectrum of RF and timing applications. The PLL can be used in digital systems where clock management is critical, as well as in analog systems for modulation and demodulation purposes.

Applications

The versatility of the CD4046BPW makes it an excellent choice for a multitude of applications, including:

• Telecommunication systems
• Signal processing
• Frequency synthesis
• Data communications
• Electronic instrumentation
