  • Forum Post: Low Jitter clock distribution

    asad1
    Dears: I need help on how to buffer/drive the output of one CDCM61001 source to 9 controllers. they all use a 75mhz input clock with very low jitter specification. Can you please recommend a buffer/driver IC. all the controllers are on SAME pcb and distance to the last one is about 8 inches...

    thaks for the detailed response: as i mentioned the current SATA controller from TI's spec section says: p.s.: the Ti's data sheet says: " A high-quality, low-jiddter differential clock source is required..., LVDS differenctial clock source, Jitter: less than 50 ps pk-pk, Duty cycle...

  • Forum Post: CDCM61001 clock generator

    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...

  • Forum Post: The problem of LMX2531 output power

    junjie fang
    I am facing a problem that when debug the PLL chip LMX2531,the output signal power is only -10 dBm.but according to the datasheet of LMX 2531,the normal output power is 0 to 5 dBm (enable the VCO output divider). the output frequency is ok and the chip can lock. who can tell me what i should do? thanks...

  • Forum Post: BQ32000 clock source

    Yogesh Palkar
    Hi, I have used BQ32000 in a circuit. I have used a 32.768kHz crystal as suggested. Is there any need to connect capacitors to the crystal? Or will the crystal simply work alone? Currently I have connected the crystal alone and the Oscillator flag bit is set to 1. If needed, what value of crystal...

    Hello Ryan Kehr sir, The crystal that is suggested is not available locally. So I have used a 32.768kHz crystal that is available locally. In general for these crystals we use a ceramic low value capacitor. As in for a microcontroller, we connect a 33pF capacitor. Now is capacitor connection necessary...

    Dear Mr. Christian Schmoeller, I've been doing a research of new devices and as a result I am using the SN74SSQEA32882 but I can hardly understand how it works. Could it be possible to get the truth table of this device? Best regards, Mauricio Cabrera Molloja
