This general-use Phase Locked Loop (PLL) offers a versatile and reliable solution for frequency synthesis in a range of electronic applications. Supporting any integer division between 1 and 32, or 1 and 64 at lower frequencies, it accommodates a wide variety of input and feedback configurations. The PLL is designed with low noise and suppresses spurious signals, ensuring clean and stable frequency outputs suitable for precision electronics.
Implemented on TSMC's 28HPC process node, this PLL can handle frequencies up to a maximum of 4.0 GHz, with a baseline as low as 500 MHz. At this minimum frequency, it operates efficiently with a power consumption of just 4mA. The compact design occupies a space of 150×150 µm, making it ideal for applications where board real estate is limited.
With auto-calibration and fast locking features, the PLL enhances system performance by quickly achieving desired frequency parameters, minimizing setup time and improving overall system responsiveness. This makes it particularly suitable for telecommunications, consumer electronics, and other data-driven industries requiring precise timing mechanisms.
