In a typical application any one of the three comparators feed an vatasheet filter network which in turn feeds the VCO input. This input is a very high impedance CMOS input. This device is similar to the CD except. Typically, when you have minimum edge rates specified it is because that signal is interacting with an internal clock or signal in a way that might generate dangerous signals.
Two signal outputs are provided, a comparator output and a phase pulse output. Those are not typos.

You are not interpreting the specifications correctly. Home Questions Tags Users Unanswered. Any voltage lower than 0. This comparator is more susceptible to noise throw- ing the loop out of lock, but is less likely to lock onto har- monics than the other two comparators.
The signal input has a self biasing amplifier allowing signals 74yc4046 be either capacitively coupled to the phase comparators with a small signal or directly coupled with standard input logic levels.
I don’t think it’s a typo, because there are others like this, such as p. The source follower is a MOS transistor whose gate is con. It can be used.
Email Required, but never shown. In general, maximum and minimum values are guaranteed, typical values are not. It can be used to 74hcc4046 the phase comparator functions and is similar to the first comparator in performance. The first parameter is giving the lowest voltage that the chip will treat as a HIGH on its input. Post as a guest Name. The SIGin input goes to a bufferso presumably that will shape things up nicely for subsequent processing.

It means most chips will ‘typically’ recognise 1. I want to know, in AC coupling signal, 744hc4046 sine wave, why it limits the frequency? I will check that it still works.
This phase detector is more susceptible to locking onto harmonics of the input fre- quency than phase comparator I, but provides better noise rejection. Especially in such an old design, like this part. I usually thought it’s the value “recommended”.

Features s Low dynamic power dafasheet I know this is a “old” part, can your suggest a newer one suited for me. You’d need more detail to be sure. Input transition time of 74HC Ask Question. In a typical application any one of the three comparators.
An inhibit pin is provided to disable the VCO and the source follower, providing a method of putting the IC in a low power state. Sign up using Facebook. This output normally is used by tying. Sign up or log in Sign up using Google.

This output normally is used by tying a resistor from pin 10 to ground, and provides a means of looking at the VCO input without loading down modifying the characteristics of the PLL filter.
