The TLV320AIC34 can also output a separate clock on the GPIO1_x pin. If the PLL is being used for the audio
data converter clock, the M and N settings can be used to provide a divided version of the PLL output. If the PLL
is not being used for the audio data converter clock, the PLL can still be enabled to provide a completely
independent clock output on GPIO1_x. The formula for the GPIO1 clock output when PLL is enabled and
CLKMUX_OUT is 0 is:
GPIO1_x = (PLLCLK_IN
×
2
×
K
×
R) / (M
×
N
×
P)
When CLKMUX_OUT is 1, regardless of whether PLL is enabled or disabled, the input to the clock output divider
can be selected as MCLK_x, BCLK_x, or GPIO2_x. Is this case, the formula for the GPIO1_x clock is:
GPIO1_x = (CLKDIV_IN
×
2) / (M
×
N), where
M = 1, 2, 4, 8
N = 2, 3, …, 17
CLKDIV_IN can be BCLK_x, MCLK_x, or GPIO2_x, selected by page 0, register 102, bits D7–D6
