Bit 7-0: Individual AIS Enable During Loss
n
(IAISEL
n
).
When this bit is set Individual AIS Enable During loss is
enabled for the individual Receiver
n
and AIS is sent to the system side upon detection a LOS of signal. Note that if
the
GC
.AISEL register bit is set, the settings in this register will be ignored.

Bit 7 to 6: PLL Clock Input [1:0] (PCLKI[1:0]).
These bits select the input into to the PLL.
00 MCLK is used.
01 RCLK1 to 8 is used based on the selection in register
CCR.
10 RCLK9 to 16 is used based on the selection in register CCR.
11 Reserved.
Bit 5: T1/E1 Clock Enable (TECLKE).
When this bit is set the TECLK output is enabled. If not set TECLK will be
disabled and the TECLK output is a LOS output. TECLK requires PLLE to be set for correct functionality.

Bit 4: Clock A Enable (CLKAE).
When this bit is set the CLKA output is enabled. If not set CLKA will be disabled
and the CLKA output is a LOS output. CLKA requires PLLE to be set for correct functionality.
Bit 3 to 2: Master Period Select [1:0] (MPS[1:0]).
These bits MPS[1:0] selects the external MCLK frequency for
the DS26334. See
Table 6-16
for details. This register when written to will also controller functionality of channels 9
to 16.
Bit 1: Frequency Select(FREQS).
In conjunction with MPS[1:0] selects the external MCLK frequency for the
DS26334. If this bit is set the external Master clock can be 1.544 MHz or multiple thereof. If not set the external
master clock can be 2.048 MHz or multiple thereof. See
Table 6-16
for details. This register when written to will
also controller functionality of channels 9 to 16.
Bit 0: Phase Lock Loop Enable(PLLE).
When this bit is set the phase lock loop is enabled. If not set MCLK will
be the applied input clock.
