They answered that they can not share formulas used to calculate PLL bandwidth and loop filter settings, and suggested to use PLL reconfiguration calculator spreadsheet (currently I can not find it). For other parameters see: https://www.altera.com/support/support-resources/operation-and-testi...
No info how to calculate the charge pump or loop filter to get a specific bandwidth. So yet another *BUMP* with the kind request from a paying customer for proper documentation. Just a hint: That order for 84 boxes=9996 pcs. 10CL010 is mine (placed through ...
Rev 0; 6/17 Abstract This document briefly covers PLL basics and explains how to use the PLL loop filter spreadsheet calculator for the MAX2769/MAX2769C. The calculator allows users to design and implement the loop filter values specific to their application.Maxim Integrated Page 1 of 8 ...
«on: I hope you're all doing well, I'm looking for a PLL/VCO chip that can extract the pixel clock from the horizontal sync pulses. The pixel clock is 21MHz, the horizontal sync is around 15KHz. I tried HC4046 and used this calculator for the passives: ...
A Kv calculator calculates a gain Kv of the VCO based on a degree of transition of an output frequency of the VCO . A loop bandwidth controller adjusts, based on the gain Kv of the VCO , a gain of a loop filter to an optimum value, and configures a desired loop bandwidth....
Third order PLL filter calculator: From Green Bay Professional Packet Radio, calculates loop filter components from PLL system parameters Hittite PLL phase noise calculator: Interactive tool allows you to see the PLL phase noise as well as the contributions from each componentOnline...
This tool helps to determine the right divider values (M, N & P) and to choose the filter type and components. This calculator will help to find out the appropriate loop bandwidth, phase margin, jitter peaking, etc. just varying the loop parameters like PFD frequency, filter components, Cha...
Check the Loop-filter Bandwidth of Your PLL Dean Banerjee As one of the most critical design parameters, the choice of loop bandwidth involves trade-offs between jitter, phase noise, lock time and spurs. The loop bandwidth that is optimal for jitter, BWJIT, can often be the best choice ...
VCO1 Loop filter loop bandwidth = 221 kHz, phase margin = 70 degrees. CLKoutX_Y_IDL = 1, CLKoutX_Y_ODL = 0. (14) Data collected using a Prodyn BIB-100G balun. Loop filter for PLL2 is C1 = 47 pF, C2 = 3.9 nF, R2 = 620 Ω, C3 = 10 pF, R3 = 200 Ω, C4 = 10 pF...
