Replacement for W245

Version 1
    Question: What do you recommend as a replacement for W245.



    We do not have a pin to pin replacement for W245.

    The W245 has a lot of options, so it would depend on specification of the use in order to come up with the best recommendation. For example, if the requirement demands center spread or down spread, and what is the input to output frequency ratio?

    The CY25100  is a good spread spectrum part with a single output, but the fact that it's programmable could be a disadvantage.

    For a non-programmable part, the following are all possibilities. Note that while the W245-30 can operate at 5V and can do spread up to 10%, none of our existing parts have that capability. They are limited to 3.3V and are limited to 3% or 3.5% spread.

    CY25560 center spread, 1:1, 25-108 MHz
    CY25561 center, 1:1, 54-166 MHz
    CY25562 center, 1:1, 54-200 MHz
    CY25568 center or down, 1:1 or 1:2 or 1:4, 4-32 MHz input
    CY25811/12/14 center or down, 1:1 or 1:2 or 1:4, 4-32 MHz input
    CY25819 down, 1:1, 8-32 MHz
