13.8 RFPLL Wrapper

The RFPLL wrapper generates two clocks:

  • spll_clk1 (PGM MHz)
    • Clock frequencies = 96 MHz/(1-255) and 64 MHz frequency choices and optional clock disable option
    • Clock ready indication
  • spll_clk2 (PGM MHz)
    • Clock frequencies = 96 MHz/(1-15) and optional clock disable option
    • Clock ready indication

Clocks are produced only when there is a request generated by the user; for clk1, it is CRU and for clk2, it is ADC charge-pump. Along with the clocks, individual clock ready is also generated, which indicates that clocks are ready for consumption.
