Refer to the description of the LOCK_8K bit (b6, 20H).
This bit, together with the DIRECT_DIV bit (b7, 20H), determines whether the DivN Divider or the Lock 8k Divider is used for
IN12:
These bits select one of the four groups of leaky bucket configuration registers for IN12:
00: Group 0; the addresses of the configuration registers are 31H ~ 34H. (default)
01: Group 1; the addresses of the configuration registers are 35H ~ 38H.
10: Group 2; the addresses of the configuration registers are 39H ~ 3CH.
11: Group 3; the addresses of the configuration registers are 3DH ~ 40H.
These bits set the DPLL required frequency for IN12:
0000: 8 kHz.
0001: 1.544 MHz (when the IN_SONET_SDH bit (b2, 09H) is ‘1’) / 2.048 MHz (when the IN_SONET_SDH bit (b2, 09H) is ‘0’).
(default)
0010: 6.48 MHz.
0011: 19.44 MHz.
0100: 25.92 MHz.
0101: 38.88 MHz.
0110 ~ 1000: Reserved.
1001: 2 kHz.
1010: 4 kHz.
1011 ~ 1111: Reserved.
For IN12, the required frequency should not be set higher than that of the input clock.
