Texas Instruments (News - Alert) Incorporated, a global analog and digital semiconductor IC design and manufacturing company, recently unveiled it LMX2581, a wideband frequency synthesizer.
The LMX2581 features integrated voltage-controlled oscillator that helps offer the industry the lowest phase noise. The synthesizer combines the capability to drive highest system performance with the flexibility of a wideband frequency synthesizer to output 50 to 3760 MHz.
Officials said that the wideband frequency synthesizer is able to outperform the competition in both phase noise and spurs by combining ultra-low noise phase-locked loop with industry's highest phase detector frequency.
Designers, with the help of this, are able to use one frequency synthesizer and support different demanding applications in wireless infrastructure, radar, medical imaging, defense and aerospace and test and measurement.
The LMX2581 also gives designers the option to bypass its internal multi-core VCO in favor of an external VCO.
The wideband frequency synthesizer integrates a delta-sigma fractional-N PLL; a multi-core VCO with tank circuit; optional frequency divider; two differential RF output buffers capable of providing 10 dBm (News - Alert) single-ended on each side; and several low-noise, high precision low dropout regulators.
When combined with high-speed analog signal chain devices from TI, like LMK04828 or LMK04800 clock jitter cleaner; AD42JB69 dual-channel, 16-bit, 250-MSPS analog-to-digital converter with JESD204B serial interface or ADC16DV160 dual-channel, 16-bit, the LMX2581 improves total link power efficiency and communication channel capacity.
