Part Number: THVD1451
Other Parts Discussed in Thread: SN65HVD01, SN65HVD10

Hi,

My customer is looking for a Precision Delay RS485 transceiver applied in 1PPS reference 1HZ clock signal in 1588 system. The chip transmission DELAY is required to be small enough. Now customer selects LTC1687, but I didn't find our products to compete the delay spec, as below. Could you help to select a proper device?

Thanks for your support.

    Minqi,

    Do you have more information about the system level requirement on this spec? For now I would recommend SN65HVD10 or SN65HVD01 for comparison.

    Please be aware that the test condition might be different. Please let me know if you have more questions.

    Regards,
