BBU DERIVATIVE FOR AD9545 / TRAY ;ROHS COMPLIANT: YES

IC/CLK FANOUT BUFFER, 2.97V-3.63V, LFCSP ROHS COMPLIANT: YES

The ADCLK948 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 ADCLK948 features eight full-swing emitter coupled logic(ECL) output drivers. For LVPECL (positive ECL) operation, bias VCC to the positive supply and VEE to ground. For ECL operation, bias VCC to ground and VEE to the negative supply.The output stages are designed to directly drive 800 mV eachside into 50 Ω terminated to VCC -2V for a total differential output swing of 1.6V. The ADCLK948 is available in a 32-lead LFCSP and specified for operation over the standard industrial temperature range of −40°C to +85°C.APPLICATIONS Low jitter clock distribution Clock and data signal restoration Level translation Wireless communications Wired communications Medical and industrial imaging ATE and high performance instrumentation
