Chapter 5: 1G/10 Gbps Ethernet PHY IP Core 5–4
Parameterizing the 1G/10GbE PHY
November 2012 Altera CorporationAltera Transceiver PHY IP Core
User Guide
10GBASE-R Parameters
Table 54 describes the parameters to specify 10GBASE-R PCS.
1Gb Ethernet Parameters
Table 55 describes the parameters to specify 1Gb Ethernet parameters.
Table 5–4. 10GBASE-R Parameters
Parameter Name Options Description
Enable IEEE 1588 Precision
Time Protocol
On/Off
When you turn this option On, the core includes logic to implement the
IEEE 1588 Precision Time Protocol.
Reference clock frequency
644.53125MHz
322.265625MHz
Specifies the clock frequency for the 1GBASE-KR PHY IP Core. The
default is 322.265625MHz.
PLL Type
ATX
CMU
Specifies the PLL type. You can specify either a CMU or ATX PLL. The
ATX PLL has better jitter performance at higher data rates than the CMU
PLL. Another advantage of the ATX PLL is that it does not use a
transceiver channel, while the CMU PLL does.
Enable additional control and
status pins
On/Off
When you turn this option On, the core includes the
rx_block_lock
and
rx_hi_ber
ports.
Enable rx_recovered_clk pin On/Off
When you turn this option On, the core includes the
rx_recovered_clk
port.
Enable pll_locked status port On/Off When you turn this option On, the core includes the
pll_locked
port.
Table 5–5. 1 Gb Ethernet
Parameter Name Options Description
Enable 1Gb Ethernet protocol On/Off
When you turn this option On, the core includes the GMII interface and
related logic.
Enable SGMII bridge logic. On/Off
When you turn this option On, the core includes the SGMII clock and
rate adaptation logic for the PCS. You must turn this option On if 1G
mode is enabled.
Enable IEEE 1588 Precision
Time Protocol
On/Off
When you turn this option On, the core includes a module in the PCS to
implement the IEEE 1588 Precision Time Protocol.
PHY ID (32 bit)
32-bit value
An optional 32-bit value that serves as a unique identifier for a particular
type of PCS. The identifier includes the following components:
Bits 3–24 of the Organizationally Unique Identifier (OUI) assigned by
the IEEE
6-bit model number
4-bit revision number
If unused, do not change the default value which is 0x00000000.
PHY Core version (16 bits)
16-bit value
Reference clock frequency
125.00MHz
62.50MHz
Specifies the clock frequency for the 1G/10GbE PHY IP Core. The
default is 125 MHz.
