Description
AI
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 VREFpin 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 VCCfor 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.ApplicationsClock and data signal restorationHigh speed converter clockingBroadband communicationsCellular infrastructureHigh speed line receiversATE and high performance instrumentationLevel shiftingThreshold detection
