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…
Part Number: CD74HC4046A Other Parts Discussed in Thread: SN74LV4046A Dear Forum,
I obsered excessive jitter at VCO_out, even if loop broken (at constant VCO control)
Jitter is ca 20 Deg peak-to peak.
Test conditions:
f0=5MHz, Ct=220pF, R2 is ca 5K (using…
Part Number: CD74HC4046A Other Parts Discussed in Thread: SN74HC4060 , Hi Team,
We would like to ask your help regarding the customer inquiry below.
Would like help defining / verifying / understanding resistor and capacitors (R1, C1, R3, C2 (R2=NC)),…
Hi Patrick,
The CD4046B is part of an older device family so unfortunately the design resources are limited. I would recommend checking the product folders for similar devices such as SN74LV4046A and CD74HC4046A and looking through the available datasheets…
Part Number: CD74HC4046A Other Parts Discussed in Thread: SN74LVC1G17 Hi Experts, My customer has question as follows. Would you please answer them? 1. This device can work well when the input frequency of SIGIN and COMPIN is 30Hz? 2. Can this device work…
Part Number: CD74HC4046A Other Parts Discussed in Thread: CD4046B , SN74LV4046A We need to use the CD74HC4046 in an already successful design of an instrument that uses an HCF4046, as the HCF4046 is now unobtanium. The PLL is used with a TI CD40103BE to…
Part Number: CD74HC4046A Hi team,
My customer is using CD74HC4046A. The schematic is as below.
Pin14 and Pin3 are all 327.68Hz. The target output on Pin4 is 1.6384MHz. But actually the output on Pin 4 cannot be locked and it is always changing.
However…
