Product Attributes

Features

• 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.
• 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)
