Unused LVPECL outputs should not be terminated to minimize power consumption. Unused inputs are internally
disabled whenever core registers 0x0010 and 0x0011 are properly provisioned. The unused inputs can be consid-
ered to be NC (no connect).

Name/Description
Receive Line Data Input [10]/Receive Line Data Input
Channel D.
In STS-48/STM-16 mode, these pins function as
receive line data input [10] at 155.52 Mbits/s.
In STS-3/STM-1 or STS-12/STM-4 mode, these pins function as
receive line data input channel D at either 155.52 Mbits/s (STS-3/
STM-1) or 622.08 Mbits/s (STS-12/STM-4).
This buffer is internally disabled when not in STS-48/STM-16
mode and channel D is disabled. This buffer is internally disabled
through proper provisioning when the input is not active.
Receive Line Data Input [11]/Receive Line Clock Channel C.
In STS-48/STM-16 mode, these pins function as receive line data
input [11] at 155.52 Mbits/s.
In STS-3/STM-1 or STS-12/STM-4 mode, these pins function as
receive line clock channel C at either 155.52 MHz (STS-3/STM-1)
or 622.08 MHz (STS-12/STM-4).
This buffer is internally disabled when not in STS-48/STM-16
mode and channel C is disabled. This buffer is internally disabled
through proper provisioning when the input is not active.
Receive Line Data Input [12]/Receive Line Data Input
Channel C.
In STS-48/STM-16 mode, these pins function as
receive line data input [12] at 155.52 Mbits/s.
In STS-3/STM-1 or STS-12/STM-4 mode, these pins function as
receive line data input channel C at either 155.52 Mbits/s (STS-3/
STM-1) or 622.08 Mbits/s (STS-12/STM-4).
This buffer is internally disabled when not in STS-48/STM-16
mode and channel C is disabled. This buffer is internally disabled
through proper provisioning when the input is not active.
Receive Line Data Input [13]/Receive Line Clock Channel B.
In STS-48/STM-16 mode, these pins function as receive line data
input [13] at 155.52 Mbits/s.
In STS-3/STM-1 or STS-12/STM-4 mode, these pins function as
receive line clock channel B at either 155.52 MHz (STS-3/STM-1)
or 622.08 MHz (STS-12/STM-4).
This buffer is internally disabled when not in STS-48/STM-16
mode and channel B is disabled. This buffer is internally disabled
through proper provisioning when the input is not active.
Receive Line Data Input [14]/Receive Line Clock Channel A.
In STS-48/STM-16 mode, these pins function as receive line data
input [14] at 155.52 Mbits/s.
In STS-3/STM-1 or STS-12/STM-4 mode, these pins function as
receive line clock channel A at either 155.52 MHz (STS-3/STM-1)
or 622.08 MHz (STS-12/STM-4).
This buffer is internally disabled when not in STS-48/STM-16
mode and channel A is disabled. This buffer is internally disabled
through proper provisioning when the input is not active.
