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…
Hi Noel,
I have made some trials. My experiments suggest the 'HC/HCT4046A VCO internal logic follows exactly the logic shown in SCHA002A TI document for the original Metal Gate CD4046 part (Fig. 8). So, it is normal to VCOout can stay both in H or L accoring…
Hi Met,
Would it be possible to attach a schematic of the CD74HC4046 or a block diagram of your test setup just to help me understand where the ripple is coming from?
It looks like in the " Implementation of FSK Modulation and Demodulation using CD74HC4046A…
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…
Part Number: CD74HC4046A Hi Team,
Our customer would like to know the minimum frequency range of CD74HC4046AM and if this device can support a frequency range of High Signal: 890Hz, Low Signal: 730 Hz.
I looked at the datasheet and found no minimum value…
