Ingress Data Bus. This data bus is used to carry ingress payload data
and in-band control words.
Ingress Data Clock. This clock is associated with the ingress data bus
(ID) and the control signal (ICTL).
Ingress Control. This signal is high when a control word is present on
the ingress data bus (ID) and it is low otherwise.
Ingress FIFO Status LVDS. These signals are used to carry ingress
round-robin FIFO status information, along with associated error detec-
tion and framing.
Ingress Status Clock LVDS. This clock is associated with the ingress
FIFO status signals (ISTA).
Ingress FIFO Status LVTTL. These signals are used to carry ingress
round-robin FIFO status information, along with associated error detec-
tion and framing.
Ingress Status Clock LVTTL. This clock is associated with the ingress
FIFO status signals (ISTA_T).
BIAS. This signal must be connected via an external pull-down 1% 3KΩ
resistor to VSS.
REF. These signals are reference for LVDS. These signals should be
connected to VDDL12.
Status Channel Control. This signal controls the status signal I/O type.
A hardware reset or software reset must be perform after changing the
level of this signal. 1 - LVDS status. 0 - LVTTL status.
QDR_A[17:0] is QDR-II Address Bus. This bus is used to transfer the
address to the QDR-II / FPGA devices. It is driven out on the rising
edge of K and K clocks during write or read operation.
