Link Ports
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 min – tDLDCH – tSLDCL). Hold skew is the
maximum delay that can be introduced in LCLK relative to
LDATA, (hold skew = tLCLKTWL min – tHLDCH – tHLDCL). Calcula-
tions made directly from speed specifications will result in
unrealistically small skew times because they include multiple
tester guardbands. The setup and hold skew times shown below
are calculated to include only one tester guardband.
ADSP-21161N Setup Skew = 1.5 ns max
ADSP-21161N Hold Skew = 1.5 ns max
Note that there is a two-cycle effect latency between the link
port enable instruction and the DSP enabling the link port.
