TI Korea (CEO Kent Chon, www.ti.com/kr) June 23, 2015 – TI (CEO Kent Chon) announced the release of the industry's lowest-power broadband RF (Radio Frequency) synthesizer. Capable of operating up to 1.34 GHz, the new LMX2571 integrates a low-noise PLLatinum™ Fractional-N type PLL (phase-locked loop) and a multi-core VCO (voltage-controlled oscillator) to generate low phase noise and spurts at just 39 mA (128 mW). This enables the LMX2571 to improve radio sensitivity and dynamic range in applications such as low-power wireless communications, handheld oscilloscopes, and signal analyzers. In addition, by integrating a frequency modulator, users can directly modulate the carrier to generate analog FM (frequency modulation) or FSK (frequency-shift-keying), making it suitable for mobile wireless applications such as land mobile radio, software-defined radio (SDR), and wireless microphones.

The LMX2571 is the industry's first RF synthesizer to integrate the ability to eliminate integer boundary spurs (IBS), enabling designers to eliminate spurious radiation from their wireless systems and maximize wireless channel utilization.

Key Features of the LMX2571 RF Synthesizer IC

· Low Operating Power: With low power consumption of 39mA (128mW), it is suitable for battery-powered applications such as terrestrial mobile wireless equipment and portable test and measurement equipment.

· Low-noise PLLatinum Fractional-N type PLL: Provides 8 times better receiver sensitivity than competing products with a PLL noise figure of merit (FOM) of -231 dBc/Hz.

· Flexible Frequency Modulation: Enhances flexibility and performance through the integration of an FSK modulator and an easy-to-use I2S interface, and meets ETSI (European Telecommunications Standard Institute) communication standards for wireless microphones and terrestrial mobile radio equipment.

· Low Spurious Radiation: By introducing a new spur removal technique to eliminate IBS, engineers can maximize the utilization of wireless channels in their designs.

· High level of integration: Reduces Bill of Materials (BOM) costs and solution footprint by integrating a low-dropout regulator (LDO), 5V charge pump, and high-speed transmit/receive (TRx) switch.

Development tools and support to reduce design time

Engineers can evaluate the performance of the LMX2571 RF synthesizer more quickly and easily by using the LMX2571EVM evaluation module (EVM). The evaluation module is available for purchase at the TI store and authorized distributors for $249.

The WEBENCH® Clock Architecture Online Design Tool simplifies design work using the LMX2571 and other TI clock and timing devices. This tool can propose single or multi-device clock tree solutions suitable for the system. It also enables PLL loop filter design and phase noise simulation, allowing designers to optimize clock tree designs based on desired performance and price points.

In the Clock and Timing Forum of the TI E2E™ Community, you can find solutions to problems, get help from fellow engineers and TI experts, and share knowledge and solve issues.

Package, supply time, and price

The LMX2571 PLLatinum RF synthesizer is currently available in a 6mm x 6mm QFN (quad flat no-lead) package, and is priced at $5.50 per 1,000-unit quantity.
