19-1248; Rev 1; 5/98 KIT ATION EVALU E L B AVAILA 10MHz to 1050MHz Integrated RF Oscillator with Buffered Outputs ____________________________Features ♦ Low-Phase-Noise Oscillator: -110dBc/Hz (25kHz offset from carrier) Attainable ♦ Operates from Single +2.7V to +5.25V Supply ♦ Low-Cost Silicon Bipolar Design ♦ Two Output Buffers Provide Load Isolation ♦ Insensitive to Supply Variations ♦ Low, 27mW Power Consumption (VCC = 3.0V) ♦ Low-Current Shutdown Mode: 0.1µA (typ) _________________General Description The MAX2620 combines a low-noise oscillator with two output buffers in a low-cost, plastic surface-mount, ultra-small µMAX package. This device integrates functions typically achieved with discrete components. The oscillator exhibits low phase noise when properly mated with an external varactor-tuned resonant tank circuit. Two buffered outputs are provided for driving mixers or prescalers. The buffers provide load isolation to the oscillator and prevent frequency pulling due to load-impedance changes. Power consumption is typically just 27mW in operating mode (VCC = 3.0V), and drops to less than 0.3µW in standby mode. The MAX2620 operates from a single +2.7V to +5.25V supply.
