The AD9517-11?provides a multi-output clock distribution function with subpicosecond jitter performance, along with an on-chip PLL and VCO. The on-chip VCO tunes from 2.30 GHz to 2.65 GHz. Optionally, an external VCO/VCXO of up to 2.4 GHz can be used.The AD9517-1 emphasizes low jitter and phase noise to maximize data converter performance, and it can benefit other applications with demanding phase noise and jitter requirements.The AD9517-1 features four LVPECL outputs (in two pairs) and four LVDS outputs (in two pairs). Each LVDS output can be reconfigured as two CMOS outputs. The LVPECL outputs operate to 1.6 GHz, the LVDS outputs operate to 800 MHz, and the CMOS outputs operate to 250 MHz.For applications that require additional outputs, a crystal reference input, zero-delay, or EEPROM for automatic configuration at startup, the AD9520 and AD9522 are available. In addition, the AD9516 and AD9518 are similar to the AD9517 but have a different combination of outputs.Each pair of outputs has dividers that allow both the divide ratio and coarse delay (or phase) to be set. The range of division for the LVPECL outputs is 1 to 32. The LVDS/CMOS outputs allow a range of divisions up to a maximum of 1024.The AD9517-1 is available in a 48-lead LFCSP and can be operated from a single 3.3 V supply. An external VCO, which requires an extended voltage range, can be accommodated by connecting the charge pump supply (VCP) to 5 V. A separate LVPECL power supply can be from 2.5 V to 3.3 V (nominal).The AD9517-1 is specified for operation over the industrial range of ?40?C to +85?C.Applications Low jitter, low phase noise clock distribution 10/40/100 Gb/sec networking line cards, including SONET, Synchronous Ethernet, OTU2/3/4 Forward error correction (G.710) Clocking high speed ADCs, DACs, DDSs, DDCs, DUCs, MxFEs High performance wireless transceivers ATE and high performance instrumentation 1AD9517 is used throughout the data sheet to refer to all the members of the AD9517 family.

The HMC1033LP6GE is a low-noise, wide-band 3.3 V clock generator IC with a fractional-N Phase Locked Loop (PLL) that features an integrated Voltage Controlled Oscillator (VCO). The device provides differential clock outputs between 25 MHz and 550 MHz range. The HMC1033LP6GE features a low noise Phase Detector (PD) and Delta- Sigma modulator, capable of operating at up to 100 MHz which permits wider loop-bandwidths and excellent spurious performance.The HMC1033LP6GE features industry leading phase noise and jitter performance, across the operating range, that enable it to improve link level jitter performance, Bit-Error-Rates (BER) and eye diagram metrics. The superior noise floor (<-162 dBc/Hz) makes the HMC1033LP6GE an ideal source for a variety of applications?such as clock references for high speed data converters, physical layer devices (PHY), serializer/deserializer (SER DES) circuits, FPGAs and processors. The HMC1033LP6GE can also be used as an LO for 10G/40G/100G optical modules and transponders, as well as primary reference clock for 10G/40G/100G line cards, and for jitter attenuation and frequency translation.The differential output of the HMC1033LP6GE can be set to either an LVPECL or LVDS compatible mode, with further output swing which makes the device flexible and compatible with a wide variety of signal level requirements. The output can be internally terminated to reduce component count and cost. The outputs could be terminated externally in LVPECL mode using standard methods such as resistors to ground. An Output Mute function allows the user to shut off the outputs, such as may be required for board testing or debugging. The LVPECL/LVDS, amplitude select and Output Mute function are all programmed SPI serial programming.The HMC1033LP6GE is designed to select between a Power Priority or a Performance Priority mode. The Power Priority setting reduces the current consumption of the part, whereas the Performance Priority setting improves the Jitter and Phase Noise performance.The 24 bit Delta-Sigma Modulator further enhances Hittite?s Exact Frequency Mode, which enables users to generate output frequencies with 0 Hz frequency error in many applications.APPLICATIONS 10G/40G/100G Optical Modules,?Transponders, Line Cards OTN and SONET /SDH Applications Data Converters,?Sample Clock Generation Cellular/4G Infrastructure High Frequency Processor/FPGA Clocks Any Frequency Clock Rate Generation Low Jitter SAW Oscillator Replacement DDS Replacement Frequency Translation Frequency Margining
