CY22381 Frequency Ranges

Version 1
    Question: What are the minimum and maximum frequency ranges for the CY22381?

     

    Answer:

    The input frequency ranges are as follows:

    CY22381FXC - Commercial - 8MHz -30MHz crystal, 1MHz -166MHz, driven.

    CY22381FXI - Industrial - 8MHz -30MHz crystal, 1MHz -150MHz, driven.

    The Output frequency ranges are as follows:

    CY22381FXC - Commercial - 8KHz - 200MHz.

    CY22381FXI - Industrial - 8KHz - 166MHz.

    Note: 8KHz can only be obtained from the buffered 1MHz reference divided by 127 (Maximum output divider value).

    The PLL Frequency Ranges are as follows:

    CY22381FXC - Commercial - 100MHz - 400MHz.

    CY22381FXI - Industrial - 125MHz - 375 MHz.

    The frequency ranges are reduced at higher temperatures for guaranteed PLL stability. The PLLs do not reliably lock at higher temperatures for which reduce the margins.
