The ADCLK950 is an ultrafast clock fanout buffer fabricated on the Analog Devices, Inc., proprietary XFCB3 silicon germanium (SiGe) bipolar process. This device is designed for high speed applications requiring low jitter.The device has two selectable differential inputs via the IN_SEL control pin. Both inputs are equipped with center tapped, differential, 100 Ω on-chip termination resistors. The inputs accept dc-coupled LVPECL, CML, 3.3 V CMOS (single-ended), and ac-coupled 1.8 V CMOS, LVDS, and LVPECL inputs. A VREFx pin is available for biasing ac-coupled inputs.The ADCLK950 features 10 full-swing emitter coupled logic (ECL) output drivers. For LVPECL (positive ECL) operation, bias VCCto the positive supply and VEEto ground. For ECL operation, bias VCCto ground and VEEto the negative supply.The output stages are designed to directly drive 800 mV each side into 50 Ω terminated to VCC− 2 V for a total differential output swing of 1.6 V.The ADCLK950 is available in a 40-lead LFCSP and specified for operation over the standard industrial temperature range of −40°C to +85°C.ApplicationsLow jitter clock distributionClock and data signal restorationLevel translationWireless communicationsWired communicationsMedical and industrial imagingATE and high performance instrumentation

TheADCMP341/ ADCMP343 consist of two low power, high accuracy comparators with a 400 mV reference in an 8-lead SOT-23 package. Operating within a supply range of 1.7 V to 5.5 V, the devices only draw 6.5 μA (typical), making them ideal for low voltage system monitoring and portable applications.Hysteresis is determined using three resistors in a string configuration with the upper and lower tap points connected to the ±INA_U and ±INA_L pins of each comparator, respectively. The state of the outputs of the comparators selects which pin is internally connected to the comparators input. Therefore, a change of state in the comparators output results in one of the inputs being switched in to the comparator and the other being switched out. This provides the user with a fully flexible and accurate method of setting the hysteresis. One input of each comparator is internally connected to the reference. The other input is available externally, via an internal mux, through pins ±INA_U or ±INA_L. The state of the output determines which of these pins is connected at any one time.The comparator outputs are open-drain with the output stage sinking capability guaranteed greater than 5 mA over temperature. The ADCMP341 has noninverting inputs and the ADCMP343 has inverting inputs. The devices are suitable for portable, commercial, industrial, and automotive applications.APPLICATIONSPortable applicationsLi-Ion monitoringHandheld instrumentsLED/relay drivingOptoisolator drivingControl systems
