General Description The MAX2750/MAX2751/MAX2752 are self-contained volt- age-controlled oscillators (VCOs) intended for use in the 2.4GHz to 2.5GHz ISM band. Each IC combines a fully integrated oscillator and output buffer in a miniature 8-pin µMAX package. The inductor and varactor elements of the tank are inte- grated on-chip, greatly simplifying application of the part. The only required external components are a couple of supply bypass capacitors. The IC provides direct connec- tion to the VCO tuning voltage input and the VCO buffer 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 buffered by an amplifier stage (internally matched to 50Ω) to provide higher output power and isolate the device from load impedance variations. The MAX2750/MAX2751/MAX2752 operate over a +2.7V to +5.5V supply voltage range. Internal regulation of the oscillator supply voltage eliminates the need for an exter- nal LDO regulator for the VCO. The IC also provides a dig- itally controlled shutdown mode to permit implementation of sophisticated power-supply management. In shutdown, the supply current is reduced to less than 1µA. ________________________Applications 802.11b DSSS WLAN 802.11 FHSS WLAN Home RF 2.4GHz Bluetooth ISM Proprietary Radio Features ♦ Guaranteed Frequency Tuning Range MAX2750: 2400MHz to 2500MHz (Zero IF) MAX2751: 2120MHz to 2260MHz (240MHz to 280MHz IF) MAX2752: 2025MHz to 2165MHz (335MHz to 375MHz IF) ♦ On-Chip Tank Circuit ♦ Internally Matched Output Buffer Amplifier ♦ Low-Current Shutdown Mode ♦ +2.7V to +5.5V Supply Voltage Range ♦ Miniature 8-Pin µMAX Package M A X 2 7 5 0 /M A X 2 7 5 1 /M A X 2 7 5 2 2.4GHz Monolithic Voltage-Controlled Oscillators OSCILLATOR CORE BIAS TUNE TUNE BYP SHDN GND OUT VCC1 VCC VCC2 GND SHDN OUT TO MIXER/ SYNTHESIZER MAX2750 MAX2751 MAX2752 Typical Operating Circuit 19-1825; Rev 1; 5/12 EVALU ATION KIT AVAIL ABLE Ordering Information PART TEMP RANGE PIN-PACKAGE MAX2750EUA+ -40°C to +85°C 8 μMAX MAX2751EUA+ -40°C to +85°C 8 μMAX MAX2752EUA+ -40°C to +85°C 8 μMAX Pin Configuration appears at end of data sheet. +Denotes a lead(Pb)-free/RoHS-compliant package.

M A X 2 7 5 0 /M A X 2 7 5 1 /M A X 2 7 5 2 2.4GHz Monolithic Voltage-Controlled Oscillators Detailed Description Oscillator The MAX2750/MAX2751/MAX2752 VCOs are imple- mented as an LC oscillator topology, integrating all of the tank components on-chip. This fully monolithic approach provides an extremely easy-to-use VCO, equivalent to a VCO module. The frequency is con- trolled by a voltage applied to the TUNE pin, which is internally connected to the varactor. The VCO core uses a differential topology to provide a stable frequen- cy versus supply voltage and improve the immunity to load variations. In addition, there is a buffer amplifier following the oscillator core to provide added isolation from load variations and to boost the output power. Output Buffer The oscillator signal from the core drives an output buffer amplifier. The amplifier is internally matched to 50Ω including an on-chip DC blocking capacitor. No external DC blocking capacitor is required, eliminating the need for any external components. The output amplifier has its own VCC and GND pins to minimize load-pulling effects. The amplifier boosts the oscillator signal to a level suitable for driving most RF mixers. Applications Information Tune Input The tuning input is typically connected to the output of the PLL loop filter. The loop filter provides an appropri- ately low-impedance source. The input may incorporate an extra RC filter stage to reduce high-frequency noise and spurious signals. Any excess noise on the tuning input is directly translated into FM noise, which can degrade the phase-noise performance of the oscillator. Therefore, it is important to minimize the noise intro- duced on the tuning input. A simple RC filter with low corner frequency is needed during testing in order to filter the noise present on the voltage source driving the tuning line. Layout Issues Always use controlled impedance lines (microstrip, coplanar waveguide, etc.) for high-frequency signals. Always place decoupling capacitors as close to the VCC pins as possible; for long VCC lines, it may be nec- essary to add additional decoupling capacitors located further from the device. Always provide a low-induc- tance path to ground, and keep GND vias as close to the device as possible. Thermal reliefs on GND pads are not recommended.
