SN74AVC1T45: Jitter Performance

Sadanori Kato

Part Number: SN74AVC1T45
Other Parts Discussed in Thread: SN74AXC1T45

Hi,

Could you please give me your advice about the jitter performance if using SN74AVC1T45 as the voltage level translator ?

Does SN74AVC1T45 affect the jitter performance(the period jitter, the cycle by cycle jitter, etc) if the 80MHz and 160MHz clock signal is translated from 1.8V to 1.2V ?
In addition, please let me know if you have the suitable solution.

Best regards,
Kato

    Hi Kato,
    We don't have test data for jitter performance of the SN74AVC1T45.

    We have done some limited testing of the SN74AXC1T45 for additive jitter, and the typical jitter output is ~160ps of total output jitter from a low jitter (~25ps) input source.

    These values aren't on the datasheet since it was not a full characterization -- it's just bench test / typical data.

    Hi Emrys-san,

    Thank you for your quick response.

    I will consult with our customer and come back to you if necessary.
