WebThe binary counter CD4040 is used for frequency division, that is, the frequency of the output signal of the PLL voltage-controlled oscillator (VCO) is 2 n times the frequency of the input signal. Because the maximum frequency division of counter CD4040 can be as high as 2 12 =4096 , the afore-described multiplication circuit is therefore capable of … Web15 de jun. de 2024 · The requirements for the VCO are these: Frequency of interest: 594.55 MHz, so only narrow tuning range required Supply voltage 5V Transistor: NPN 2SC5773 (have loads of these), datasheete here varicap: HVU202 (have loads of these), datasheet here Output level: 0dBm into 50ohm load (It will be later tuned by LMX2315 PLL) Web6 de jan. de 2013 · I've to set up a VCO which gives as follows.
