ADS58H43: Can ADS58H43 be used for 138.24MSPS?

Part Number: ADS58H43

Hi team,

My customer wants to use the device ADS58H43 with 138.24MSPS, but the datasheet says the min sample clock is 184MSPS. So can we use it for 137.24MSPS?

Thanks.

  • Yes, it is possible. Reference the notes in the datasheet about special register writes to go below 184. Copied below for reference:

    (2) The minimum functional clock speed can be 10 MSPS after writing the following special modes: address 4Ah, value 01h; address 62h,
    value 01h; address 92h, value 01h; and address 7Ah, value 01h. See the SPECIAL MODE[17:14] bits in Table 4 of the Serial Interface
    Registers section.
