GENERAL DESCRIPTION

The ADCLK905 (one input, one output), ADCLK907 (dual one

input, one output), and ADCLK925 (one input, two outputs) are

ultrafast clock/data buffers fabricated on the Analog Devices, Inc.,

proprietary XFCB3 silicon germanium (SiGe) bipolar process.

The ADCLK905/ADCLK907/ADCLK925 feature full-swing

emitter coupled logic (ECL) output drivers. For PECL (positive

ECL) operation, bias V

For NECL (negative ECL) operation, bias V

The buffers offer 95 ps propagation delay, 7.5 GHz toggle rate,

10 Gbps data rate, and 60 fs random jitter (RJ).

The inputs have center tapped, 100 Ω, on-chip termination

resistors. A V

The ECL output stages are designed to directly drive 800 mV

each side into 50 Ω terminated to V

differential output swing of 1.6 V.

The ADCLK905/ADCLK907/ADCLK925 are available in

16-lead LFCSP packages.
