1 / 8 page  General Description The MAX2754 self-contained, linear modulation, volt- age-controlled oscillator (VCO) is intended for use in the 2.4GHz to 2.5GHz ISM band, particularly for FSK modulation systems that utilize a direct frequency-mod- ulation transmit architecture. This device features a lin- ear modulation input in addition to the standard frequency tuning input. The frequency tuning range of 1145MHz to 1250MHz (1/2 LO) also supports an IF up to 110MHz with low side LO. The VCO is based on Maxim’s proprietary monolithic VCO technology, where all VCO components are integrated on-chip, including the varactor and inductor. The MAX2754 linear modulation input offers a means to directly FM modulate the VCO with a constant modula- tion sensitivity over the tuning voltage input range. Typical frequency deviation is -500kHz/V which is linear to ±4% over the guaranteed frequency limits. The tun- ing input voltage range is +0.4V to +2.4V and the oscil- lator frequency is factory adjusted to provide guaranteed limits. The oscillator signal is buffered by an output amplifier stage (internally matched to 50 Ω) to provide higher output power and isolate the oscillator from load impedance variations. The MAX2754 operates over a +2.7V to +5.5V supply range. This device also provides a digitally controlled shutdown mode to permit implementation of sophisti- cated power-supply management. In shutdown, the supply current is reduced to 0.2µA. Even when active, power consumption is a modest 41mW. The MAX2754 is packaged in the miniature 8-pin µMAX to offer the world’s smallest, complete 2.4GHz direct- modulation VCO solution.
