Output Path Signals

Table 19: Output Path Signals

Output path signals are signals that are available when you set the Pin Type parameter to either Output or

Bidirectional.

Signal Name Direction Width Description

oe_from_core Input

Quarter-rate: 4 x PIN_WIDTH

Half-rate: 2 x PIN_WIDTH

Full-rate: 1 x PIN_WIDTH

Core rate data enable to be

output. Synchronous to the

core_clk output from the IP

core.

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

Core rate data to be output.

Synchronous to the core_clk

output from the IP core.

strobe_out_in Input

Quarter-rate: 8

Half-rate: 4

Full-rate: 2

Strobe pattern to be output.

Synchronous to the core_clk

output from the IP core.

Note: This path is always

DDR.

strobe_out_en Input

Quarter-rate: 4

Half-rate: 2

Full-rate: 1

Enable output strobe. Synchro‐

nous to the core_clk output

from the IP core.

data_out/data_io Output/

Bidirectional

• 1 to 48 if data configuration is

Single Ended

• 1 to 24 if data configuration is

Differential

Data output to pin. Synchro‐

nous to the strobe_out or

strobe_io output from the IP

core.

If the Pin Type parameter is set

to Output, the data_out

signals are used. If the Pin

Type parameter is set to

Bidirectional, the data_io

signals are used.
