GENERAL DESCRIPTION
The TSA5059A is a single chip PLL frequency synthesizer designed for satellite tuning systems up to 2.7 GHz.

FEATURES
• Complete 2.7 GHz single chip system
• Optimized for low phase noise
• Selectable divide-by-two prescaler
• Operation up to 2.3 GHz without divide-by-two prescaler (satellite zero-IF applications) and up to 2.7 GHz with divide-by-two prescaler
• Selectable reference divider ratio
• Selectable crystal or comparison frequency output
• Four selectable charge pump currents
• Four selectable I2C-bus addresses
• Standard and fast mode I2C-bus
• I2C-bus compatible with 3.3 and 5 V microcontrollers
• 5-level Analog-to-Digital Converter (ADC)
• Low power consumption
• Three I/O ports and one output port.

APPLICATIONS
• Satellite zero-IF and non-zero-IF tuning systems
• Digital set-top boxes.
