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 digital-to-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 , 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 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 40C to +125C.
