The HMC704 has been designed for the best phase noise and lowest spurious content possible in an integrated synthesizer. Fabricated in a SiGe BiCMOS process, this Fractional-N frequency synthesizer consists of a very low noise digital phase detector, VCO divider, reference divider and a precision controlled charge pump.Ultra low in-close phase noise and low spurious allows wide loop bandwidths for faster frequency hopping and low micro-phonics. Exact frequency mode with 24-bit fractional modulator provides the ability to generate fractional frequencies with zero frequency error, an important feature for Digital Pre-Distortion systems.The serial interface offers read back capability and is compatible with a wide variety of protocols.Applications Microwave Point-to-Point Radios  Base Stations for Mobile Radio (GSM, PCS, DCS, CDMA, WCDMA) Wireless LANs, WiMAX Communications Test Equipment CATV Equipment Automotive

The ADCLK905 (one input, one output), ADCLK907 (dual oneinput, one output), and ADCLK925 (one input, two outputs) areultrafast clock/data buffers fabricated on the Analog Devices, Inc.,proprietary XFCB3 silicon germanium (SiGe) bipolar process.The ADCLK905/ADCLK907/ADCLK925 feature full-swing emitter coupled logic (ECL) output drivers. For PECL (positive ECL) operation, bias VCC to the positive supply and VEE to ground. For NECL (negative ECL) operation, bias VCC to ground and VEE to the negative supply.The buffers offer 95 ps propagation delay, 7.5 GHz toggle rate, 10 Gbps data rate, and 60 fs random jitter (RJ).The inputs have center tapped, 100 Ω, on-chip termination resistors. A VREF pin is available for biasing ac-coupled inputs.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 ADCLK905/ADCLK907/ADCLK925 are available in 16-lead LFCSP packages.Applications Clock and data signal restoration and level shifting Automated test equipment (ATE) High speed instrumentation High speed line receivers Threshold detection Converter clocking
