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.

An evaluation kit is available:  MAX2620EVKIT
