• One single-ended clock
input signal
Provides read/write access to all LVDS and
single-ended channels, where the channels are
grouped by connector. This CLIP conveys
parallel data at high speeds. You can access
the LVDS data and direction lines using a U16
data type, you can access the LVDS PFI lines
using a U8 data type, and you can access the
single-ended PFI lines using a Boolean
control. In the U8 data type, the top four bits
are unused. Each LVDS line, PFI line, and
clock output is connected to an OSERDES or
ISERDES block that serializes or deserializes,
respectively, the signal by a factor of six by
default. Therefore, with every regional clock
cycle, the NI 6587 reads or writes six samples
to or from the ISERDES or OSERDES
blocks. All OSERDES and ISERDES blocks
are set to double data rate (DDR) mode.
The following table lists the NI 6587 SMA connector signals and corresponding NI FlexRIO
FPGA module signals necessary for designing custom component-level IP (CLIP).

The following table lists the NI 6587 DDC connector signals and corresponding NI FlexRIO
FPGA module signals necessary for designing custom component-level IP (CLIP). The
_CC
suffix on signals identifies channels that can receive a regional clock.
