Link Ports —Receive, Transmit
For Link Ports, see Table 19, Table 20, Figure 22, and
Figure 23. Calculation of link receiver data setup and hold,
relative to link clock, is required to determine the maximum
allowable skew that can be introduced in the transmission path,
between LDATA and LCLK. Setup skew is the maximum delay
that can be introduced in LDATA, relative to LCLK (setup
skew = tLCLKTWH minimum – tDLDCH –tSLDCL). Hold skew is the
maximum delay that can be introduced in LCLK, relative to
LDATA (hold skew = tLCLKTWL minimum + tHLDCH –tHLDCL). Cal-
culations made directly from speed specifications result in
unrealistically small skew times, because they include multiple
tester guardbands.
Note that there is a two-cycle effect latency between the link port
enable instruction and the DSP enabling the link port.

1 LACK goes low with tDLALC relative to rise of LCLK after first nibble, but does not go low if the receiver’s link buffer is not about to fill.
