TSA5055T/C3

The TSA5511 is a versatile single-chip Phase-Locked Loop (PLL) frequency synthesizer engineered for television tuning applications. This integrated circuit operates up to 1.3 GHz, making it suitable for modern TV tuner designs. It features I2C-bus programming for easy control and configuration, allowing for precise selection of oscillator frequencies and programming of output ports.

Designed for efficiency, the TSA5511 consumes low power, operating at 5V and drawing only 35 mA. Key features include an in-lock flag for monitoring loop status, a varicap drive disable function, and low radiation characteristics. The device offers address selection for Picture-In-Picture (PIP) and DBS tuner applications, supporting up to three addresses. It also incorporates an analog-to-digital converter and provides 8 bus-controlled ports, with 5 available on the TSA5511T variant.

This synthesizer is ideal for TV tuners and VCR tuners, providing a reliable and integrated solution for frequency synthesis in consumer electronics. Its design facilitates integration into compact systems while maintaining performance.
