ADCLK948BCPZ-REEL7

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 centre tapped, differential, 100 ohm on-chip termination resistors. The inputs accept dc-coupled LVPECL, CML, 3.3V CMOS (single-ended), and ac-coupled 1.8V CMOS, LVDS, and LVPECL inputs. Application includes low jitter clock distribution, clock and data signal restoration, level translation, wireless communications, wired communications, medical and industrial imaging, ATE and high performance instrumentation.

• 2 selectable differential inputs, on-chip input terminations
• Input differential range from 0.4V to 3.4V p-p (±1.7V between input pins)
• 50 ohm typical single-ended mode (VCC -VEE = 3.3V and TA = 25°C)
• 100 ohm typical differential mode (VCC -VEE = 3.3V and TA = 25°C)
• 50Kohm common mode (open VTx, VCC -VEE = 3.3V and TA = 25°C)
• 20µA typical input bias current (VCC -VEE = 3.3V and TA = 25°C)
• 10mV typical hysteresis (VCC -VEE = 3.3V and TA = 25°C)
• 4.8GHz maximum output frequency typical (VCC -VEE = 3.3V and TA = 25°C)
• Propagation delay is 245ps maximum at (VICM = 2V, VID = 1.6V p-p)
• 32 lead LFCSP package, operating temperature range from -40°C to +85°C
