    Phase frequency detector and charge pump current!

    Hi, I am using an IC where it has PLL integrated along with Phase Frequency detector. In the data sheet there are some rating about "Charge pump current". What this current mean? How can I physically interpret this current to my desired out put. Does it something to do with the speed of the...

    Problem with "CDC 7005 High performance clock synthesizer and jitter cleaner"

    Problem with "CDC 7005 High performance clock synthesizer and jitter cleaner" I am working with these ICs for the 1st time. So might be noob questions :) ....sorry for that, but here are the questions:- Q1: What is the reference clock input for this IC? Data sheet says, there should be another...

    Convert from PECL to Sine wave.

    I will need that Sine wave to run a LASER Driver. This LASER Driver and ADC have to be synchronized. So, I would prefer to use the same source.

    Convert from PECL to Sine wave.

    Can I convert my PECL signal coming out from a VCXO to a Sine wave? The frequency should be around 80-100 MHz. I want to use Toyocom TCO−2111T 122.88-MHz PECL VCXO along with CDC7005 by TI and my ADC is ADS6149 by TI Any suggestion? Sincerely, Mustahsin

    Need help to design a Sine curve multiplier

    Hi, Sounds convincing!!...Thank you very much to both of u!:-D ---------- Post added at 14:25 ---------- Previous post was at 12:28 ---------- Btw....my Sine function signal will have to be synchronous with the ADC.....So, if I will use two different sources, then the Synchronisation...

    Need help to design a Sine curve multiplier

    Hi, Thank you Keith for the answer.....but, for my application jitter is one of the main issues.....my Point to point jitter limit should be around 10Ps.....so can u suggest any particular product?

    Need help to design a Sine curve multiplier

    I need an IC that can multiply a Sine wave having around 80MHz by 3 to make it upto 240MHz. This 240 MHz will be needed for an ADC. Low jitter desirable!...So that IC should take the Sine wave as an input and make the output as logic.
