Table 18.   GTS Serial Lite IV Intel® FPGA IP Parameter Description
Parameter Value Default Description
General Design Options
PMA data rate 1 Gbps16 Gbps 10.3125 Gbps Specifies the effective data rate at the output of the transceiver incorporating transmission and other overheads. The value is calculated by the IP by rounding up to 1 decimal place in Gbps unit.
PMA mode
  • Duplex
Duplex The supported direction is duplex.
Number of PMA lanes 1 – 4 1 Select the number of lanes. For simplex design, the supported number of lanes is 1 – 4.
PMA reference clock frequency 27.5 MHz379.84375 MHz, depending on the selected transceiver data rate. 156.25 MHz Specifies the reference clock frequency of the transceiver.
System PLL reference clock frequency 170 MHz Available when the System PLL frequency selection is set to Custom, regardless of the transceiver type.
System PLL frequency
  • N 9
  • Custom
322.265625 MHz Specifies the system PLL clock frequency.
Custom System PLL frequency 322.265625 MHz Specifies custom system PLL frequency. This field is enabled when System PLL frequency is set to Custom.
Alignment Period 128 – 65536 128 Specifies the alignment marker period.

The value must be x2.

User Interface
Streaming mode
  • FULL
  • BASIC
Full Select the data streaming for the IP.

FULL: This mode sends a start-of-packet and end-of-packet cycle within a frame.

BASIC: This is a pure streaming mode where data is sent without a start-of-packet, empty, and end-of-packet to increase bandwidth.
