Bits 7 to 5: PLL Clock Select (PCLKS[2:0]).
These bits determine the RCLK that is to be used as the input to the
PLL. If an LOS is detected for the channel that RCLK is recovered from, the PLL switches to MCLK until the LOS is
cleared. When the LOS is cleared, the selected RCLK is used again. See Table 5-15 for RCLK selection.

Bit 4: T1/E1 Clock Select (TECLKS).
When this bit is set the T1/E1 clock output is 2.048MHz. When this bit is
reset the T1/E1 clock rate is 1.544MHz.
Bits 3 to 0: Clock A Select (CLKA[3:0]).
These bits select the output frequency for CLKA pin. See Table 5-16 for
available frequencies.
