Table 6: AC Specification type Out B.ttl Pins
(50 MHz)
Test Load Conditions: 500
, 15 pF.
Note 1: Pin skew is measured from the earliest rising edge of the group to the latest rising edge of the group.
Note 2: Delay is the intrinsic delay between the TTL drivers switching and the PECL driver switching. This is measured from
the OutA.pecl signal at the signal swing mid-point to max output of the OutB.ttl signal’s rising edge
Table 7: AC Specification type Out C.ttl Pins
(25 MHz)
Test Load Conditions: 500
, 15 pF.
Note 1: Pin skew is measured from the earliest rising edge of the group to the latest rising edge of the group.
Note 2: Spread is the absolute difference between the rising edge of any OutC.ttl signal and the rising edge of any OutB.ttl
signal
