Timestamp Options
Table 3-4: Timestamp Options Parameters
ParameterValueName
Timestamp
Turn on this parameter to enable time stamping
on the transmitted and received frames.
On/OffEnable timestamping
Turn on this parameter to insert timestamp on
PTP messages for 1-step clock based on the TX
Timestamp Insert Control interface.
This parameter is disabled if you do not turn on
Enable timestamping.
On/OffEnable PTP 1-step clock
Use this parameter to set the width in bits for
the timestamp fingerprint on the TX path. The
default value is 4 bits.
—Timestamp fingerprint width
PCS/Transceiver Options
The PCS/Transceiver options are enabled only if your core variation includes the PCS function.
Table 3-5: PCS/Transceiver Options Parameters
ParameterValueName
PCS Options
Configures the PHY ID of the PCS block.—PHY ID (32 bit)
Turn on this option to add the SGMII clock and
rate-adaptation logic to the PCS block. This
option allows you to configure the PCS either in
SGMII mode or 1000Base-X mode. If your
application only requires 1000BASE-X PCS,
turning off this option reduces resource usage.
In Cyclone IV GX devices, REFCLK[0,1] and
REFCLK[4,5] cannot connect directly to the
GCLK network. If you enable the SGMII bridge,
you must connect ref_clk to an alternative
dedicated clock input pin.
On/OffEnable SGMII bridge
Transceiver Options—apply only to variations that include GXB transceiver blocks
