FLL1_Con

trol_3

15:0

FLL1_THETA

[15:0]

0018h

FLL1 Fractional multiply for FREF

This field sets the numerator (multiply) part of the

FLL1_THETA / FLL1_LAMBDA ratio.

Coded as LSB = 1.

If updated while the FLL is enabled, the new value is

only effective

when a ‘1’ is written to FLL1_CTRL_UPD.

R372

(0174h)

FLL1_Con

trol_4

15:0

FLL1_LAMBDA

[15:0]

007Dh

FLL1 Fractional multiply for FREF

This field sets the denominator (dividing) part of the

FLL1_THETA / FLL1_LAMBDA ratio.

Coded as LSB = 1.

FLL1_FRATIO

[3:0]

FLL1 FVCO clock divider

0h = 1

1h = 2

2h = 3

3h = 4

…

Fh = 16

FLL1_REFCLK_

DIV [1:0]

FLL1 Clock Reference Divider

00 = 1

01 = 2

10 = 4

11 = 8

MCLK (or other input reference) must be divided down

to <=13.5MHz.

For lower power operation, the reference clock can be

divided down further if desired.

FLL1_REFCLK_S

0000

FLL1 Clock source

0000 = MCLK1

0001 = MCLK2

0011 = SLIMCLK

0100 = FLL1

0101 = FLL2

0110 = FLL3

1000 = AIF1BCLK

1001 = AIF2BCLK

1010 = AIF3BCLK

1011 = AIF4BCLK

1100 = AIF1LRCLK

1101 = AIF2LRCLK

1110 = AIF3LRCLK

1111 = AIF4LRCLK

All other codes are Reserved

FLL1_GAIN [3:0]

0000

FLL1 Gain

0000 = 1

0001 = 2

0010 = 4

0011 = 8

0100 = 16

0101 = 32

0110 = 64

0111 = 128

1000 to 1111 = 256

R385

(0181h)

FLL1_Syn

chroniser_

FLL1_SYNC_EN

FLL1 Synchroniser Enable

0 = Disabled

1 = Enabled

This should be set as the final step of the FLL1

synchroniser enable sequence, i.e., after the other

synchroniser registers have been configured.
