Abstract:
An integrated circuit includes a first die and a second die. The first die comprising a first phase-locked loop (PLL) and the second die comprising a second PLL. The integrated circuit includes a shared loop filter, wherein the first PLL in the first die is combined with the shared loop filter to form a first PLL feedback loop, the second PLL in the second die is combined with the shared loop filter to form a second PLL feedback loop and the shared loop filter is configured to provide configurable bandwidths to each of the first PLL feedback loop and the second PLL feedback loop.
