The ADCLK905/ADCLK907/ADCLK925 are ultrafast SiGe ECL clock/data buffers. They feature a propagation delay of 95 ps, a toggle rate of 7.5 GHz, a typical output rise/fall time of 60 ps, and a random jitter of 60 fs. They are suitable for clock and data signal restoration and level shifting, automated test equipment (ATE), high-speed instrumentation, high-speed line receivers, and converter clocking applications.
The ADCLK905, ADCLK907 and ADCLK925 are ultrafast SiGe clock/data buffers offering full‑swing ECL output drivers. They support both PECL and NECL operation, provide on‑chip terminations, and are available in 16‑lead LFCSP packages.
Key features include 95 ps typical propagation delay, 7.5 GHz toggle rate, 60 fs random jitter, a supply range of 2.5 V‑3.3 V, and an industrial temperature range from –40 °C to +125 °C. The document provides electrical characteristics, pin configurations, typical application circuits, and performance graphs.
