TSA5059 Overview
The TSA5059 is a single chip PLL frequency synthesizer designed for satellite and terrestrial tuning systems up to 2.7 GHz. The RF preamplifier drives the 17-bit main divider enabling a step size equal to the parison frequency, for an input frequency up to 2.7 GHz. A fixed divide-by-two additional prescaler can be inserted between the preamplifier and the main divider to give a software patibility with TSA5059...
