Link Ports —2 × CLK Speed Operation
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:

For ADSP-21060L, specification is 5 ns min.
For ADSP-21062, specification is 4 ns min, for ADSP-21060LC, specification is 4.5 ns min.
LACK goes low with t
For ADSP-21060L, specification is 6 ns min, 18 ns max. For ADSP-21060C, specification is 6 ns min, 16.5 ns max. For ADSP-21060LC, specification is 6 ns min, 18.5 ns max.

Hold skew is the maximum delay that can be introduced in
LCLK relative to LDATA:
Calculations made directly from 2 speed specifications will
result in unrealistically small skew times because they include
multiple tester guardbands.
