2.3.2.2. Output Path Signals

The following table provides the output path signals in PHY Lite for Parallel Interfaces Intel® FPGA IP for Agilex™ 5 E-Series devices.

Table 19.  Output Path SignalsOutput path signals are signals that are available when you set Pin Type to either Output or Bidirectional. The <n> in the signal names in the following table represents the group number in the IP.
Signal Name Direction Width Description
group_<n>_data_from_core Input

Quarter rate DDR: 8 x PIN_WIDTH

Half rate DDR: 4 x PIN_WIDTH

Full rate DDR: 2 x PIN_WIDTH

Quarter rate SDR: 4 x PIN_WIDTH

Half rate SDR: 2 x PIN_WIDTH

Full rate SDR: 1 x PIN_WIDTH

Data signal from the Intel FPGA core.

Synchronous to the core_clk_out output from the IP.

group_<n>_oe_from_core Input

Quarter rate: 4

Half rate: 2

Full rate: 1

Output enable signal from the FPGA core.

Synchronous to the core_clk_out output from the IP.

Each group has separate output enable.

group_<n>_strobe_out_en Input

Quarter rate: 4

Half rate: 2

Full rate: 1

Strobe output enable from the FPGA core.

Synchronous to the core_clk_out output from the IP.

Each group has separate strobe enable.

group_<n>_strobe_from_core Input

Quarter rate: 8

Half rate: 4

Full rate: 2

Strobe pattern from core. Simple strobe pattern can be generated by this signal with 8’h55 values.
group_<n>_data_out / group_<n>_data_io Output 1 to 22

Data output from the IP. Synchronous to the group_<n>_strobe_out or group_<n>_strobe_io output from the IP.

If the Pin Type is set to Output, the group_<n>_data_out signals are used.

If the Pin Type is set to Bidirectional, the group_<n>_data_io signals are used.

group_<n>_data_out_n / group_<n>_data_io_n Output 1 to 22

Differential data output from the IP.

Synchronous to the group_<n>_strobe_out_n or group_<n>_strobe_io_n output from the IP.

group_<n>_strobe_out/ group_<n>_strobe_io Output 1

Positive output strobe from the IP.

If the Pin Type is set to Output, the group_<n>_strobe_out signal is used.

If the Pin Type is set to Bidirectional, the group_<n>_strobe_io signal is used.

group_<n>_strobe_out_n / group_<n>_strobe_io_n Output 1

Negative output strobe from the IP.

This is used if the Strobe Configuration is set to Differential.

If the Pin Type is set to Output, the group_<n>_strobe_out_n signal is used.

If the Pin Type is set to Bidirectional, the group_<n>_strobe_io_n signal is used.
