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, after…
Part Number: CD74HC4046A
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 on…
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 an…
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 datasheet…
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 .
another…
Part Number: CD74HC4046A Other Parts Discussed in Thread: CDCE913 Hi，
CD74HC4046APWR is connected to CDCE913, and the circuit diagram is shown below. In most cases, the PC2out pin does not output and the output remains at a low level. Please help analyze…
Part Number: CD74HC4046A Other Parts Discussed in Thread: SN74LV4046A Hello,
I have a question about the data sheet(Data sheet acquired from Harris Semiconductor SCHS204J) of CD74HC4046A.
Regarding Phase Comparator 3 (PC3), Figure 7 of the data sheet…
Part Number: CD74HC4046A Other Parts Discussed in Thread: SN74LV4046A , CD4046B Hi team,
I'm looking to replace the HEF4046B with either the CD74HC4046A or SN74LV4046A. They seem to be pin-to-pin options, but there's a difference with regards to pin…
