Part Number: CD74HC4046A The case:
Mount the PLL CD74HC4046A with one resistor R1, as example 14 Kohm, when a external sinewave signal is applied to pin 14 the PLL locks over a large frequency area without any disturbances.
I like to have a start…
Part Number: CD74HC4046A I tried to find the ESD level for TI VPN CD74HC4046AE on the quality, reliability & packaging information file. It said see datasheet. Information is missing from the datasheet.
Can you tell me what the ESD level is for TI VPN…
Part Number: CD74HC4046A Hello Experts,
We encounter an issue while testing of the PLL IC CD74HC4046A. We are getting the expected output of Phase Comparator 1 Output and Phase Comparator 3 Output as shown below images, but for Phase Comparator 2 Output…
Part Number: CD74HC4046A Tool/software: Dear Forum,
I would like to ask wheter PC2 comparator hf CD74HC4046A is dead-zone free?
PC2 has a tree-state voltage output and goes to Hi-Z state when PLL reach locked condition (phase difference is 0 deg,…

Tool/software:
Hello,
I am new in designing FM, and I designed an FM Modulation + Demodulation though I did not know that there was an analog and digital mod. If there's anyone have an idea on how to design or get started…
Part Number: CD74HC4046A Tool/software: I am new to PLL design, and I am designing a local oscillator using the CD74HC4046A PLL IC. I have a schematic setup and a reference signal of 15.8 MHz from a waveform generator, but I cannot get the correct value…
Part Number: CD74HC4046A Tool/software: Dear Forum,
My application is sensitive to VCO output level when it is stopped by INH=H.
I observed it randomly goes to H or L when INH activated.
Device Appliaction report and an old National MM74HC4046A…
Part Number: CD74HC4046A Tool/software: We are planning to use TI part CD74HC4046AM96 as an alternate of Onsemi MPN#MC74HC4046ADG but it got failed during evaluation(reported by Designer). Want to hear from TI whether any other customer has faced any…
Part Number: CD74HC4046A Hi, I have been trying to demodulate an FSK signal at 9600 baud, and 4.8kHz frequency deviation. I don't mind what the carrier frequency of the signal is, although the higher it is the better. I have followed the application note…
Part Number: CD74HC4046A hi all,
i am detecting phase shift between two signals feeding to COMMON IN and SIG in . i had issue where PC2out was dead . I solved issue by adding 2k /2k to 5v and gnd . i dont understand why it needs resistors their .…
