Part Number: CD74HC7046A Hello, I am working on a project using a CD74HC7046A PLL as an FM demodulator for a 10.7MHz IF with a frequency deviation of +/-100kHz. I seem to be having some trouble following the datasheets Application Information section…
Part Number: CD74HC7046A Hello I used R1-270K, R2-220K, C1-100PF to get 500KHZ, I want to lock the frequency to the mains (50HZ). I did a frequency division and I used PC2. Can you help me calculate LPF values? (R3, R4, C2). Best Regard Itamar
Part Number: CD74HC7046A Other Parts Discussed in Thread: MSP-EXP430FR2311 Hello Guys,
Good day.
Our customer have built a locking circuit resolution of +/- 3 microseconds with the CD74HC7046A. Is it possible to reach higher resolution with this component…
Part Number: CD74HC7046A Other Parts Discussed in Thread: CD74HC4049 , Hi Experts,
We are using a "Phase-Locked Loop with VCO and Lock Detector " whose part number is "CD74HC7046AM"
I am unable to find ibis models for simulation.
Could…
Part Number: CD74HC7046A I suspect that the Die backside on this HCMOS device would be floating and not biased to either Vcc or Gnd.
Can you confirm ?
Thx
Other Parts Discussed in Thread: CD74HC7046A Hello,
I have a project requiring a VCO, and the CD74HC7046A seems to be a good choice, but it is CMOS, and not TTL. Is there a TTL equivalent for this circuit?
Best regards,
Ion
Part Number: CD74HCT7046A Other Parts Discussed in Thread: CD74HC7046A Date Sheet of CD74HC7046A/CD74HCT7046A mentions minimum center frequency of 12MHz. It also mentions "For a frequency range of 100kHz to 10MHz, the lock detector capacitor should be…
Other Parts Discussed in Thread: CD74HC7046A hello,
What is the max. current that I can take direct out from PC2OUT (pin 13) of the CD74HC7046A to the loop-filter (R3/C2)?
in the datasheet I found:
Features
Fanout (Over Temperature Range) - Standard Outputs…
Hey Danilo, This E2E post does a good job of explaining the resistor and capacitors and the datasheet can help you find the values that you need :
