3. When a set-up time is specified between a PECL input and a PECL clock, the

set-up time is the time in nanoseconds from the crossing point of the

differential input to the crossing point of the differential clock.

4. When a hold time is specified between a PECL input and a PECL clock, the

hold time is the time in nanoseconds from the crossing point of the differential

clock to the crossing point of the differential input.

Notes on Output Timing:

1. Output propagation delay time is the time in nanoseconds from the 1.4 Volt

point of the reference signal to the 1.4 Volt point of the output.

2. Maximum output propagation delays are specified with a 50 pF load on the

outputs, except for TXD+/- and TXC+/-. Maximum output propagation delays

for TXD+/- and TXC+/- are specified with a 30 pF load.

3. Differential output propagation delay time is the time in nanoseconds from the

crossing point of the reference signal to the crossing point of the output.
