Device Feature and Function DFC – Dynamic Frequency Control
▪ OTP programmable–4 different feedback fractional dividers (4 VCO frequencies) that apply to PLL2. ▪ ORT (overshoot reduction) function will be applied automatical y during the VCO frequency change. ▪ Smooth frequency incremental or decremental from current VCO to targeted VCO base on DFC hardware pins selection. ©2017 Integrated Device Technology, Inc 3 December 18, 2017 Document Outline Description Typical Applications Features Output Features Key Specifications Block Diagram Power Group Output Source Selection Register Setting Tables Pin Assignments Figure 1.
