TLK2711-SP: Clock information

May

Part Number: TLK2711-SP

Hi Team,

I would want further information about TLK2711 chronogram. The chronogram described in the datasheet expect that the clock GTX_CLK arrives before VDD/VDDA. Is this mandatory? Can you please provide more details about this.

Thank you.

Regards,
May

    Hi May,

    This is not mandatory, but is shown to demonstrate the conditions necessary to constitute a power on reset condition.  If GTX_CLK is provided after power up, I would recommend keeping the enable pin low until GTX_CLK is present.  Once GTX_CLK is present, enable can be set high.  This creates a reset condition.

    Thanks,

    Drew
