1. The TRU-600 meets all SONET.SDH requirements for jitter transfer and jitter tolerance mask characteristics at the stan-
dard SONET transmission rates.
2. Measured with respect to Vcc with load R
L
of 50 ohms to Vcc-2v. ECL voltage levels are specified for dc measurement.
An additional tolerance of 50 mV should be added for dynamic measurement.
3. Allowable input clock frequency variation with respect to the nominal clock frequency (F
N
) over the entire operating
temperature range.
4. Alignment of clock and data outputs.
5. Measured at 20% to 80% levels.
6. Time required to achieve valid data and clock outputs with an input transition density of at least 50%.
7. Measured with an input data pseudorandom word (PRW) 2
