Signals
Table 4–5 through Table 4–11 list the I/O signals used in the receiver MegaCore
function. The active low signals are suffixed by _n .

Description
SPI-4.2 differential receive clock. Double-data rate clock
synchronous to rctl and rdat .
SPI-4.2 differential receive control.
rctl
LVDS Input
rdclk
When set to a logic 1, the word on rdat is a control word. When
set to a logic 0, the word on rdat is a payload word.
rdat[15:0]
LVDS Input
SPI-4.2 differential receive data bus. Bus carries packets/cells or
in-band control words.
SPI-4.2 receive status clock. This signal uses a regular LVTTL
rsclk

rsclk
(rdint_clk)
data pin instead of a dedicated output clock pin. Derived from
rdclk . Active if rdclk is active.
SPI-4.2 receive status channel. Indicates the downstream
device’s FIFO buffers’ fill level to the upstream device’s scheduler.

Description
Derived from rdclk . Signals infixed with _rd_ are
synchronous to this clock. Active if rdclk is active.
System clock. Signals infixed with _ry_ are synchronous to
this clock.
Active low asynchronous reset to all internal logic, including
rxreset_n
Input
Asynchronous Atlantic FIFO buffers. Refer to “Reset Structure” on

Static
Asynchronous
Fixed output information signal that contains the current
AOT number for the release.
Locked signal directly from fast PLL in ALTVDS for full rate
variations, or enhanced PLL in quarter-rate variations.
Asynchronous reset signal directly to fast PLL in ALTVDS for
ctl_rx_pll_areset
Input
Asynchronous full rate variations, or enhanced PLL in quarter-rate
variations.
