An inhibit pin is provided. In general, maximum and dataeheet values are datahseet, typical datahseet are not. I know this is a “old” part, can your suggest a newer one suited for me. 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. It is saying it will always recognise 2. I can’t open the size you posted. Why the typical value may bigger than the max.
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. In a very old chip – CDB’s datasheeti find this:.
Home Questions Tags Users Unanswered. Especially in such an old design, like this part. View PDF for Mobile. Phase comparator II is an edge sensitive digital sequential network. This comparator is more susceptible to noise throw. In a typical application any one of the three comparators feed an external filter network which in turn feeds the VCO input.

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 to be either capacitively coupled to the phase comparators with a small signal or directly coupled with standard input logic levels. Input transition time of 74HC Ask Question. I don’t think it’s a typo, because there are others like this, such as p.

I thought there are some relation to the word “typical”. This phase detector is more susceptible to locking onto harmonics of the input fre- quency than phase comparator I, but provides better noise rejection. Or if can recommend another better chip.
Two signal outputs are provided, a comparator. This input is a very high impedance CMOS input which also drives the source follower. Thanks 74hcc4046 your reply. In a typical application any one of the three comparators.

In 74HC’s datasheetsection “Recommended operating conditions”, i find this. Any voltage higher than 2. HC is featured on www. II, i thought dtaasheet is for DC coupled signal. Home Questions Tags Users Unanswered.
This device contains a low power linear voltage controlled oscillator VCOa source follower, dayasheet three phase comparators. And at kHz sine wave input, the minimum sensitivity is mV max.
I think you mean ” badbeetles. In a very old chip – CDB’s datasheeti find this: Sign up or log in Sign up using Google. The SIGin input goes to a bufferso presumably that will shape things up nicely for subsequent processing.
