-New ADF4113HV extends charge pump power supply voltage up to 16.5 Volts, compared to most PLL synthesizer ICs which are limited to 5 or 6 Volts. -Extended voltage provides wider tuning range for broadband frequency synthesis.

Norwood, MA (06/04/2007) - Analog Devices, Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal processing applications, today announced the industry’s first PLL synthesizer with a high-voltage charge pump. The ADF4113HV integer-N frequency synthesizer was specifically designed for use in applications with voltage controlled oscillators (VCOs) that have high tuning voltages, and features a high voltage charge pump (15V). The ADF4113HV is ideally suited for the design of products such as private mobile radios (PMR) and communications test equipment. With the addition of the new charge pump, a high voltage VCO can be controlled directly through a passive loop filter, thereby eliminating the need for active loop filters and as a result, reducing BOM cost as well as noise and current consumption.

The ADF4113HV is fully pin-compatible with the company’s other integer-N PLL synthesizers and complements the ADF4113 in those applications which need a large tuning range but where the cost and component count of an active loop filter are undesirable or impractical. The ADF4113HV is also supported by the Analog Devices’ popular ADIsimPLL™ design and simulation software, which greatly simplifies and streamlines the loop filter design and is available for free download at

“Analog Devices continues to demonstrate its leadership in RF by adding to its vast product portfolio and delivering devices that set new levels of performance,” said Christian Kermarrec, vice president, RF and wireless systems. “With the addition of the ADF4113HV, designers can get the wide operating voltage range and level of accuracy they need, while also saving them significant time and cost.”

About the ADF4113HV PLL Synthesizer
The ADF4113HV operates in frequencies in the range of 200 MHz to 4 GHz and with a power supply ranging from 2.7 V to 5.5 V. The device consists of a low noise phase frequency detector (PFD), a precision high voltage charge pump, a programmable reference divider, programmable A and B counters, and a dual-modulus prescaler (P/P + 1). A simple 3-wire interface controls all of the on-chip registers. The ADF4113HV also features two selectable charge pump currents and digital lock detectors.

Pricing and Availability
The ADF4113HV is available now and is priced at $2.46 per unit in quantities of 1,000.
