That bandwidth covers the fastest serial data converters, FPGA reference clocks, and RF sampling ADCs — the part doesn't limit the clock tree before the signal reaches the load. It accepts a differential clock input and delivers a differential output in ECL, NECL, or PECL logic levels, selectable via the supply voltage. The 1:1 fanout keeps the signal path simple — one clean copy of the input, no added skew from a splitter. ## Supply and temperature range The part operates from a single 2.375V to 3.63V supply, so it can run directly off a 2.5V or 3.3V rail without an extra LDO. ## Package and layout notes Housed in a 16-lead LFCSP with exposed pad measuring 3x3 mm. The exposed paddle must be soldered to a ground plane for thermal and electrical performance — at 7.5 GHz, a floating paddle adds inductance that degrades signal integrity.","metaTitle":"ADCLK905BCPZ-R7 Analog Devices 7.5 GHz Clock Buffer SiGe","metaDescription":"ADCLK905BCPZ-R7 from Analog Devices: 7.5 GHz max frequency, 1:1 fanout, ECL/NECL/PECL outputs, -40°C to 125°C, 16-LFCSP.

The ADCLK905 provides a 1:1 fanout (one input to one output), while the ADCLK925 offers a 1:2 fanout (one input to two outputs). If your design needs to drive multiple loads from a single clock source, the ADCLK925 saves an extra buffer stage."},{"question":"Is ADCLK905BCPZ-R7 compatible with 3.3V logic?","answer":"Yes. The supply range of 2.375V to 3.63V covers both 2.5V and 3.3V rails. When powered at 3.3V, the output swings PECL levels that are directly compatible with 3.3V CML or LVPECL inputs on downstream devices.
