DESCRIPTION:
driver with inverting outputs. The clock driver provides a high-speed
interface between cards operating at TTL logic levels and back-planes
operating at GTLP logic levels. GTLP provides reduced output swing
(<1V), reduced input threshold levels, and output edge-rate control to
minimize signal setting times. The GTLP816 is a derivative of the Gunning
Transceiver Logic (GTL) JEDEC standard JESD8-3 and incorporates
internal edge-rate control, which is process, voltage, and temperature
(PVT) compensated.
