ADCLK907BCPZ-R2

时钟缓冲器 Ultrafast SiGe ECL

Product Details

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 VCC to the positive supply and VEE to ground. For NECL negative ECL operation, bias VCC to ground and VEE to the negative supply.

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 VREF pin is available for biasing ac-coupled inputs.

The ECL output stages are designed to directly drive 800 mV each side into 50 Ω terminated to VCC − 2 V for a total differential output swing of 1.6 V.

The ADCLK905/ADCLK907/ADCLK925 are available in 16-lead LFCSP packages.
