The ADCLK905/ADCLK907/ADCLK925 are ultrafast SiGe ECL clock/data buffers featuring 95 ps propagation delay, 7.5 GHz toggle rate, 60 ps typical output rise/fall and 60 fs random jitter (RJ).
The ADCLK905 (single‑output), ADCLK907 (dual‑output) and ADCLK925 (1‑to‑2 fan‑out) are ultrafast SiGe ECL clock/data buffers designed for high‑speed instrumentation, automated test equipment, and converter clocking. They feature on‑chip terminations, wide temperature range, and support both PECL and NECL operation.
Key specifications include a typical propagation delay of 95 ps, a 7.5 GHz toggle rate, and 60 fs rms random jitter. The devices are supplied in a 16‑lead LFCSP package and operate from a 2.5 V to 3.3 V supply across –40 °C to +125 °C.
