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…
Part Number: CD74HC4046A Other Parts Discussed in Thread: SN74LV4046A Hi team
I want to use the PLL-IC at 6.78MHz.
I purchased the CD74HC4046A, which can operate at 18MHz (when Vcc = 5V ) according to the "features" on the top page of the data sheet…
Part Number: CD74HC4046A Hello,
I'm hoping to find some clarification on Figure 4 of the component datasheet (shown below).
The figure lists the following equation as the characteristic equation of the Vdemout behavior:
VDEMOUT = VPC2OUT= (VCC/4π…
Part Number: CD74HC4046A Hi team,
We need to do 4x frequency circuit by CD74HC4046A, input range is 100Hz~500kHz, output is 400Hz to 2MHz, this is big frequency range, is it available for CD74HC4046A?
I know this may tough for CD74HC4046A, so would you help…
Part Number: CD74HC4046A Other Parts Discussed in Thread: CD4046B , SN74LV4046A Hi,
my customer has the following question:
I would like to implement a HC4046 in one of our circuit designs to monitor a voltage and convert it into a frequency. So I just…
