Hai,

I need the vhdl/verilog codes for the all digital delay locked loop ,with any simple architecture which can work on few Mhz of frequency or the website ,materials(pdf).

20 points for a good code


 

Hi,

Could any one send me the concept behind the "All digital delay locked loop" and also if you have worked on it do send me your codes(vhdl/verilog) so that i can understand it easily .

ALL digital delay locked loop (ADDLL) consists of generally
1.Phase detector
2.digtially controlled delay unit(which includes fine + coarse delay unit).
3.digital controller for generating digital code word.
4.Buffers.
 
Not a Code But a liitle Information on DLL....

**broken link removed**
 

There is a very good section (with examples) on all
digital PLL's in the following book:

Roland E. Best
Phase-Locked Loops. Design, Simulation and Applications.
ISBN 0-07-134903-0
 

Even i need the code for DLL or ADPLL.

plz anyone UPLOAD

thanks
 

Hi,

I had already seen it ,but it is not much help as i need to know about digital (or all digital ) delay locked loop (DLLs) .IT contains the VCDL(voltage controlled delay line) for analog DLL and DCDL(digitally controlled delay line) for digital DLL, instead of VCO(voltage controlled oscillator).

I need to know more precise information.
 

Hi, jilinhai2002

can u send me the dpll code
