Web3.1. Basic PLL The principal elements in a basic PLL are illustrated in the PLL block diagram in Figure 1. The dividers may not necessarily be needed but are included for generality. A reference frequency, fREF, is divided down by the input reference divider R and applied to the phase detector, PD, here shown as a mixer. Likewise, the output ... WebNov 12, 2024 · Their different division ratios are generated by using a fractional $\Delta \Sigma $ modulator (DSM) and a dynamic element matching (DEM) block. To reduce the divider power, this article also proposes a way to achieve spatial averaging using only one divider and phase selection.

We have two of these attributes, depending on the QPLL: SDM0DATA and SDM1DATA. Its valid range goes from 0 to 2^24-1. Thus only 24 bits [23:0] are needed to describe this attribute.
