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 detect for the channel that RCLK is recovered from, the PLL will switch to MCLK until the LOS is
cleared. When the LOS is cleared RCLK will be used again. See Table 6-20 for RCLK selection. MC.PCLKI[1:0]
must be set to ‘01’ or ‘10’ in order for these settings to take effect.

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 6-21 for
available frequencies. For best jitter performance, select MCLK as the source for CLKA and input a 2.048MHz
MCLK.
