ADS42LB69: SYNCIN input structure

Part Number: ADS42LB69

I could not find anything in the data sheet regarding the input impedance and bias of the SYNC inputs.  Am I correct in assuming it is a high impedance differential receiver lightly biased to 1.2V?  

  • Calvin,

    I am checking with the design team for this info. Based on the driver used on the EVM, it appears this is an LVPECL input. I will reply back with the design teams response.

    Regards,

    Jim

  • Hi,

    The SYNC inputs (SYNCP and SYNCM) are self-biased by device at common mode voltage of 0.95V through internal 1.1k ohms biasing resistors.
