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 ?， 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 ?40°C to +125°C.
