19-0831; Rev 0; 6/07 2.4GHz Monolithic Voltage-Controlled Oscillator for Automotive MAX2750AUA General Description Features The MAX2750AUA is a self-contained voltage-controlled Guaranteed Frequency Tuning Range: oscillator (VCO) intended for use over the 2370MHz 2370MHz to 2470MHz to 2470MHz frequency range. The IC combines a fully On-Chip Tank Circuit integrated oscillator and output buffer in a miniature 8-pinµMAX® package. Internally Matched Output Buffer Amplifier The inductor and varactor elements of the tank are inte- Low-Current Shutdown Mode grated on-chip, greatly simplifying application of the part. +2.7V to +5.5V Supply Voltage Range The only required external components are a couple ofsupply bypass capacitors. The IC provides direct connec- Miniature 8-Pin µMAX Package tion to the VCO tuning voltage input and the VCO buffer -40°C to +125°C Temperature Range output. The tuning voltage input range is +0.4V to +2.4V,and the oscillator frequency tuning range is factory adjust-ed to provide guaranteed limits. The output signal is Ordering Information buffered by an amplifier stage (internally matched to 50)to provide higher output power and isolate the device from PIN- PKG load impedance variations.
