Parameter Range Description
Enable rx_enh_
fifo_align_clr
port (Interlaken)
On / Off Enables the rx_enh_fifo_align_clr input port. Only used for
Interlaken. This signal is synchronous to rx_clkout.
Table 2-13: Interlaken Frame Generator Parameters
Parameter Range Description
Enable
Interlaken frame
generator
On / Off Enables the frame generator block of the Enhanced PCS.
Frame generator
metaframe
length
5-8192 Specifies the metaframe length of the frame generator. This
metaframe length includes 4 framing control words created by
the frame generator.
Enable Frame
Generator Burst
Control
On / Off Enables frame generator burst. This determines whether the
frame generator reads data from the TX FIFO based on the
input of port tx_enh_frame_burst_en.
Enable tx_enh_
frame port
On / Off Enables the tx_enh_frame status output port. When the
Interlaken frame generator is enabled, this signal indicates the
beginning of a new metaframe. This is an asynchronous signal.
Enable tx_enh_
frame_diag_
status port
On / Off Enables the tx_enh_frame_diag_status 2-bit input port.
When the Interlaken frame generator is enabled, the value of
this signal contains the status message from the framing layer
diagnostic word. This signal is synchronous to tx_clkout.
Enable tx_enh_
frame_burst_en
port
On / Off Enables the tx_enh_frame_burst_en input port. When burst
control is enabled for the Interlaken frame generator, this signal
is asserted to control the frame generator data reads from the
TX FIFO. This signal is synchronous to tx_clkout.
Table 2-14: Interlaken Frame Synchronizer Parameters
Parameter Range Description
Enable
Interlaken frame
synchronizer
On / Off When you turn on this option, the Enhanced PCS frame
synchronizer is enabled.
Frame synchron‐
izer metaframe
length
5-8192 Specifies the metaframe length of the frame synchronizer.
Enable rx_enh_
frame port
On / Off Enables the rx_enh_frame status output port. When the
Interlaken frame synchronizer is enabled, this signal indicates
the beginning of a new metaframe. This is an asynchronous
signal.
