Custom Transceiver PHY
June 2012 1.7
■ Added the following QSF settings to all transceiver PHY:
XCVR_TX_PRE_EMP_PRE_TAP_USER
,
XCVR_TX_PRE_EMP_2ND_POST_TAP_USER
, and 11
new settings for GT transceivers.
■ Added reference to Stratix V Transceiver Architecture chapter for detailed explanation of the
PCS blocks.
■ Updated definition of
rx_enapatternalign
: It is edge sensitive in most cases; however, if
the PMA-PCS interface width is 10 bits, it is level sensitive.
■ Added definition for
rx_byteordflag
output status signal which is created when you
enable the byte ordering block.
■ Changed the default value for
XCVR_REFCLK_PIN_TERMINATION
from
DC_coupling_internal_100_Ohm to AC_coupling.
■ Added arrows indicating Transceiver Reconfiguration Controller IP Core connection to block
diagram.
■ Changed the maximum frequency of
phy_mgmt_clk
to 150 MHz if the same clock is used
for the Transceiver Reconfiguration Controller IP Core.
■ Added the following restriction in the dynamic reconfiguration section: three channels share
an Avalon-MM slave interface which must connect to the same Transceiver Reconfiguration
Controller IP Core.
