Parameter Settings
You can parameterize the Altera LVDS SERDES IP core using the IP Parameter Editor.
General Settings Tab
Description
Value
Parameter
Specifies the functional mode of the interface.
• TX
• RX Non-DPA
• RX DPA-FIFO
• RX Soft-CDR
Functional mode
Specifies the number of serial channels in the
interface.
• Decrement one channel for the dedicated
reference clock pin (
refclk
) for TX, RX
Non-DPA, and RX DPA. Not using the
dedicated reference clock pin may
contribute to higher jitter.
• Decrease by one channel for the TX
outclock pin (
tx_outclock
) if used.
• 1 to 72 for TX
• 1 to 24 for RX Non-
DPA
• 1 to 24 for RX DPA-
FIFO
• 1 to 12 for RX Soft-
CDR
Number of channels
Specifies the data rate (in Mbps) of a single
serial channel. The value is dependent on the
Functional mode parameter settings.
150.0 to 1600.0
Data rate
Specifies the serialization rate or deserializa-
tion rate for the LVDS interface.
3, 4, 5, 6, 7, 8, 9, and 10
SERDES factor
When enabled, the IP core bypasses the PLL
and the interface is driven with a clock pin.
This feature is not supported in
the current version of the Quartus
II software.
Note:
—
Use clock-pin drive
When enabled, the IP core uses legacy top-
level names that are compatible with
ALTLVDS_TX and ALTLVDS_RX IP cores.
—
Use backwards-compatible port
names
