  • Wiki Page: CDCM6100x - Driving the oscillator input of the CDCM6100x with a LVCMOS input signal

    Fritz
    Question: Can the XIN input be driven from a 3.3V CMOS input signal? Answer: Generally, the XIN input can be driven with a single-ended input signal, but it needs to be AC coupled . This is because the input stage is self-biased and also does some oscillator related calibration that would not tolerate...

    Question: The CDCM61004 Datasheet states on page 20: "for proper operation, the LVCMOS reference should be available and fairly stable by the time the power supply voltages or the RSTN pin voltage on CDC... reaches 2.27V." --> What does the word stable mean? Answer: Upon releasing...

    Lee, Apologies for the delay on the response for this. Do you still need the above addressed or did you find the information you needed for the CDCM61002? Best regards, Brad

    Lee, For a reference schematic for the CDCM61002, please take a look at the EVM User's Guide for the CDCM6100x below: http://www.ti.com/litv/pdf/scau027a We provide a snapshot of a reference circuit using the device on page 7 of this document. In addition, the EVM User's Guide gives...

    M-Dizzle
    Hi, I'm looking at the CDCM61001 clock generator (also 61002 and 61004) and I have a query over the dc rating of ferrite bead (Ref Figure 19 from CDCM61001 datasheet). This will be connected to the analog supplies (VCC_PLL1, _PLL2 and _VCO), but I'm not sure what current I should rate this...

    Fritz
    Hello Adrian, Please first allow me to appologize. We must have overlooked your message and just now saw that it wasn't responded to yet. Concerning your question, yes, connecting the 3.3V LVCMOS output directly to this 2.5V LVTTL input presents no problem as the TLK2501 was designed in particular...

    This Excel tool is a really nice to check: (A) if the CDCM6100x can output a certain frequency (B) what crystal frequency is necessary and how to configure the control pins Revision Control: 01/17/2012: Rev 1.0

    Fritz
    Hi Yannick, you might possibly find the XTAL not starting up at all. HOwever, we find that XTAL manufacturer put a very big guardband around their spec, meaning when they spec 80 Ohm, most likely their real ESR will be a lot lower than 50 Ohm. I recommend you to have one of your boards tested for...
