The ADCLK914 is an ultrafast clock/data buffer fabricated on the Analog Devices, Inc., proprietary, complementary bipolar (XFCB-3) silicon-germanium (SiGe) process. The ADCLK914 features high voltage differential signaling (HVDS) outputs suitable for driving the latest Analog Devices high speed digitalto-analog converters (DACs). The ADCLK914 has a single, differential open-collector output.
The ADCLK914 buffer operates up to 7.5 GHz with a 160 ps propagation delay and adds only 110 fs random jitter (RJ). The input has a center tapped, 100 Ω, on-chip termination resistor and accepts LVPECL, CML, CMOS, LVTTL, or LVDS (ac-coupled only). A VREF pin is available for biasing ac-coupled inputs.
The HVDS output stage is designed to directly drive 1.9 V each side into 50 Ω terminated to VCC for a total differential output swing of 3.8 V.
The ADCLK914 is available in a 16-lead LFCSP. It is specified for operation over the extended industrial temperature range of −40°C to +125°C.

Evaluation Kits (1)
The ADCLK914 clock buffer is very fast, making it important to use adequate high bandwidth instruments to evaluate it. To that end, the evaluation board is fabricated using a high quality dielectric material between layers to maintain high signal integrity. Transmission line paths are kept as close to 50 Ω as possible.
