ADCLK954BCPZ

The ADCLK954BCPZ is an ultrafast clock fanout buffer fabricated on Analog Devices' proprietary XFCB3 SiGe bipolar process. It features two selectable differential inputs controlled via the IN_SEL pin, each with on-chip 100 Ω differential termination resistors. The device accepts DC-coupled LVPECL, CML, and 3.3 V CMOS signals, as well as AC-coupled 1.8 V CMOS, LVDS, and LVPECL inputs. A VREFx pin is provided for biasing AC-coupled inputs.

The ADCLK954BCPZ provides 12 full-swing LVPECL output drivers, with a maximum operating frequency of 4.8 GHz and ultra-low broadband random jitter of 75 fs rms. It operates from a 3.3 V supply (2.97 V to 3.63 V) over the industrial temperature range of -40°C to +85°C. The outputs can be configured for LVPECL or ECL operation by appropriate biasing of VCC and VEE.

The device is housed in a 40-lead LFCSP (6 mm × 6 mm) with exposed pad for thermal management, and is surface-mount compatible. Applications include low-jitter clock distribution, clock and data signal restoration, level translation, and use in wireless and wired communications, medical imaging, ATE, and high-performance instrumentation.
