  • RE: SN74LV4046A: Output of PC2_OUT and PCP_OUT

    Resolved
    Hi Atsushi, If phase comparator 2 is being used, then two consecutive COMP_IN rising edges would cause phase comparator 2 to down-count twice and set PC2_out low, indicating that the COMP_IN frequency is faster than SIG_IN. Similarly, if there are two…

  • RE: SN74LV4046A: SN74LV4046A as frequency multiplier

    Hi Matteo, I am not sure, maybe the 4046 is sensitive to layout, maybe your problem will get fixed if you have a real board instead of bread board.

  • SN74LV4046A: PLL Jitter issue

    Part Number: SN74LV4046A New to using a PLL, but have a circuit that converts 30Hz square wave to 12.288 MHz We have fine-tuned the circuit, but still have 20-40uS jitter between reference (SIN) and CIN. Ideas to reduce jitter? Better clock gen IC options…

    Part Number: SN74LV4046A Other Parts Discussed in Thread: LM3881 Hi, I have a customer who wants to find a simple delay chip, such as input a high level at 0 time, this chip will output the signal after 20ms delay, and it needs 3.3V power supply, please…

  • SN74LV4046A: SN74LV4046A : PC2 Average Output voltage vs Input Phase Difference Characteristic

    TI Thinks Resolved
    Part Number: SN74LV4046A Hello, when I compare PC2 Average Output voltage vs Input Phase Difference Characteristic, I obtain with my mockup, to the one in the datasheet, I have a negative slope instead of a positive slope (while PC1 and PC3 have a positive…

  • SN74LV4046A: Select frequency range of VCO

    TI Thinks Resolved
    Part Number: SN74LV4046A Other Parts Discussed in Thread: CDCE913 Hi, Is it possible to narrow down the frequency lock range to 118 – 125 kHz? I see that Resistor R1 and capacitor C1 determine the frequency range of the VCO but cant find much details…
