The ADCLK944 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 a differential input equipped with center-tapped, differential, 100 Ω on-chip termination resistors. The input can accept dc-coupled LVPECL, CML, 3.3 V CMOS (single-ended), and ac-coupled 1.8 V CMOS, LVDS, and LVPECL inputs. A VREF pin is available for biasing ac-coupled inputs.The ADCLK944 features four 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 ECL 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 ADCLK944 is available in a 16-lead LFCSP and is 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

Real Time Clock

The AD-SYNCHRONA14-EBZ is an ideal self-contained device to use in evaluation and prototyping of applications that need a highly accurate frequency and phase-controlled source clock. It is designed around the Analog Devices AD9545 and HMC7044 and greatly simplifies clock distribution and multi-channel synchronization in complex systems. It is intended to be used by trained professionals in a laboratory environment, and not intended as an end product for commercial use. It can be taken as a complete reference design and customised as required for any end customer applications. Full design details are made available free of charge.

The AD-SYNCHRONA14-EBZ comes in a 1U mechanical form factor. Using popular industry connector SMA and TwinAX interfaces most labs will already have the needed cables.

With its internal OCXO it can operate in standalone mode or be fed from a choice of external sources, such as 3 separate high speed differential clock inputs, a 10MHz reference and 1PPS. This flexibility combined with the capability to select either of the internal VCXO options of 100MHz or 122.88MHz, gives almost unlimited choice for the frequency of interest and accuracy needed for a wide variety of application areas.
