The HMC835LP6GE is a low noise, wide band, Fractional-N PLL that features an integrated VCO with a fundamental frequency of 2020 to 4100 MHz, and an integrated VCO Output Divider (divide by 2/4/6/.../60/62) that together enable the HMC835LP6GE to generate frequencies from 33 MHz to 4100 MHz. Integrated Phase Detector (PD) and a deltasigma modulator capable of operating at up to 100 MHz enable wider loop-bandwidths, faster frequency changes along with excellent spectral performance.Two independent RF outputs, with independent gain control, enable the HMC835LP6GE to distribute identical frequency and phase signals to multiple destinations, at optimal signal levels tailored to each output.External VCO input, allows the HMC835LP6GE to lock external VCOs, and enables cascaded LO architectures for MIMO radio applications. Two separate Charge Pump (CP) outputs enable separate loop filters optimized for both integrated and external VCOs, and seamless switching between integrated or external VCOs during operation. Programmable RF output phase feature can further phase adjust and synchronize multiple HMC835LP6GEs enabling scalable MIMO and beam-forming radio architectures.Additional features include configurable output mute function that mutes RF outputs during frequency changes, Exact Frequency Mode that enables the HMC835LP6GE to generate fractional frequencies with 0 Hz frequency error, and the ability to synchronously change frequencies without changing the phase of the output signal.Applications MIMO Radio Architectures Cellular Infrastructure Cellular backhaul Communications Test Equipment CATV Equipment Phased Array Applications?

The ADM2xxE is a family of robust RS-232 and V.28 interface devices which operates from a single +5 V power supply. These products are suitable for operation in harsh electrical environments and are compliant with the EU directive on EMC (89/336/ EEC). Both the level of emissions and immunity are in compliance. EM immunity includes ESD protection in excess of ±15 kV on all I-O lines (1000-4-2), Fast Transient Burst protection (1000-4-4) and Radiated Immunity (1000-4-3). EM emissions include radiated and conducted emissions as required by Information Technology Equipment EN55022, CISPR22.All devices fully conform to the EIA-232E and CCITT V.28 specifications and operate at data rates up to 230 kbps. Shutdown and Enable control pins are provided on some of the products. The shutdown function on the ADM211E disables the charge pump and all transmitters and receivers. On the ADM213E the charge pump, all transmitters, and three of the five receivers are disabled. The remaining two receivers remain active thereby allowing monitoring of peripheral devices. This feature allows the device to be shut down until a peripheral device begins communication. The active receivers can alert the processor which can then take the ADM213E out of the shutdown mode. Operating from a single +5 V supply, four external 0.1 µF capacitors are required. The ADM206E is available in a 24-pin SO package. The ADM207E and ADM208E are available in 24-pin DIP, SO, SSOP and TSSOP packages. The ADM211E and ADM213E are available in 28-pin SO, SSOP and TSSOP packages. All products are backward compatible with earlier ADM2xx products facilitating easy upgrading of older designs.APPLICATIONS Laptop computers Notebook computers Printers Peripherals Modems

The OPx177 family consists of very high precision, single, dual, and quad amplifiers featuring extremely low offset voltage and drift, low input bias current, low noise, and low power consump-tion. Outputs are stable with capacitive loads of over 1000 pF with no external compensation. Supply current is less than 500 μA per amplifier at 30 V. Internal 500 Ω series resistors protect the inputs, allowing input signal levels several volts beyond either supply without phase reversal.Unlike previous high voltage amplifiers with very low offset voltages, the OP1177 (single) and OP2177 (dual) amplifiers are available in tiny 8-lead surface-mount MSOP and 8-lead narrow SOIC packages. The OP4177 (quad) is available in TSSOP and 14-lead narrow SOIC packages. Moreover, specified performance in the MSOP and the TSSOP is identical to performance in the SOIC package. MSOP and TSSOP are available in tape and reel only.The OPx177 family offers the widest specified temperature range of any high precision amplifier in surface-mount packaging. All versions are fully specified for operation from −40°C to +125°C for the most demanding operating environments.Applications for these amplifiers include precision diode power measurement, voltage and current level setting, and level detection in optical and wireless transmission systems.
