A good example comes via a project from [Scott, AJ4VD], a very simple frequency counter that uses a single 74 series chip at its business end, and counts to over 100MHz. The chip in question is a ...
The ll_pll1421s01_ln14lpp_34201 is a 1.8V/0.8V dual supply-voltage phase locked loop (PLL) with a wide-output-frequency-range for frequency synthesis. It consists of a phase frequency detector (PFD), ...
Changing this 50MHz Rigol oscilloscope into its larger, more expensive brother just became quite a bit easier. When we originally looked at this hack it required pulling some capacitors off of the ...
