EIA608 line 21 decoding
timing range (typical)
Normal setting 9.7 ms to 11.3 μ s
Early setting 8.9 ms to 10.5 μ s
Late setting 10.3 ms to 11.8 μ s
Normal setting exceeds requirements of
EIA608 decoder speci
fi cation by 60%. Early
and late settings provided to allow decoding
of even more extreme signals.
Table 8: Timing display characteristics
Characteristic Performance requirement Reference information
Input timing relative to External Reference Display of V & H timing offset graphically
and numerically. One clock cycle
resolution. Patented proprietary display.
Timing Display Zero De fi nition Vertical timing conforms to
SMPTE168-2002. Timing zero is equivalent to nominal zero
delay on TG700. Also agrees with signal
that shows minimal shift on the waveform
display when go from internal to external.
Link B to Link A Display of dual link timing skew.
Uncertainty of ± 1.5 clocks or 20 ns.
Input Timing Reference to Other Input For Simultaneous inputs, allows selection
of other channel as reference.
