ADCLK944 is a SiGe clock fanout buffer with four LVPECL outputs. It operates at a voltage range of 2.5V to 3.3V and a frequency of 7.0 GHz. It features low jitter, on-chip input terminations, and is suitable for applications such as low jitter clock distribution, clock and data signal restoration, level translation, wireless communications, wired communications, medical and industrial imaging, ATE, and high performance instrumentation.
The ADCLK944 is an ultrafast clock fanout buffer fabricated on Analog Devices' proprietary XFCB3 silicon germanium (SiGe) bipolar process. It is designed for high-speed applications requiring low jitter and features a differential input with on-chip center-tapped, differential 100 Ω termination resistors. The device accepts dc-coupled LVPECL, CML, and 3.3 V CMOS inputs, as well as ac-coupled 1.8 V CMOS and LVDS inputs.
