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…
Part Number: CD74HCT7046A Other Parts Discussed in Thread: CD74HCT4046A , Hi E2E,
What is the difference between CD74HCT7046A and CD74HCT4046A? Which is the most suitable device to lock a 1 kHz square wave? Is there a PLL integrated circuit with a sinusoidal…
Part Number: CD74HCT7046A We are now using HCT7046 for FM demodulator design, the sch is same as datasheet FIGURE 1. LOGIC DIAGRAM as below, R3=3.3k, C2=470pF. signal frequency(intermediate frequency) applied on pin14 is 10.7MHz, 280kHz bandwidth, power…
Part Number: CD74HCT7046A Hi Team,
Our customer is using CD74HCT7046A for an FM demodulation circuit. While the output demodulation noise is too high: around 50~60mVpp.
Is there any method to decrease the noise amplitude?
Or any method to move the demodulation…
where to find nonlinear phase-slip phase lock loops or frequency lock loops with specified frequency capture range, say of about 0.01 x f0 to 0.1 x f0, where f0 is the VCO center frequency?
Other Parts Discussed in Thread: CD74HCT7046A I need to know how to design the low pass filter whose output is then pass on to the VCO input of the CD74HCT7046A PLL chip. By determining the values for the resistor R3 and R4 & capacitor C2. i can also be…
