The PLL can be turned on via page 0 / register 5, bit D7. The variable P can be programmed via page 0 /
register 5, bits D6–D4. The variable R can be programmed via page 0 / register 5, bits D3–D0. The
variable J can be programmed via page 0 / register 6, bits D5–D0. The variable D is 14 bits and is
programmed into two registers. The MSB portion can be programmed via page 0 / register 7, bits D5–D0,
and the LSB portion is programmed via page 0 / register 8, bits D7–D0. For proper update of the D divider
value, page 0 / register 7 must be programmed first, followed immediately by page 0 / register 8. Unless
the write to page 0 / register 8 is completed, the new value of D does not take effect.
When the PLL is enabled, the following conditions must be satisfied:
When the PLL is enabled and D = 0, the following conditions must be satisfied for PLL_CLKIN:
(7)
When the PLL is enabled and D
≠ 0, the following conditions must be satisfied for PLL_CLKIN:
(8)
The PLL can be powered up independently from the DAC block, and can also be used as a
general-purpose PLL by routing its output to the GPIO output. After powering up the PLL, PLL_CLK is
available typically after 10 ms.
The clock for the codec and various signal processing blocks, CODEC_CLKIN, can be generated from the
MCLK input, BCLK input, GPIO input, or PLL_CLK (page 0 / register 4, bits D1–D0).
If CODEC_CLKIN is derived from the PLL, then the PLL must be powered up first and powered down last.
Table 5-29 lists several example cases of typical PLL_CLKIN rates and how to program the PLL to
achieve a sample rate fS of either 44.1 kHz or 48 kHz.
