TSA5060A - NXP

TSA5060A 1.3 GHz I2C-bus controlled low phase noise frequency synthesizer

The TSA5060A is a single chip PLL frequency synthesizer designed for terrestrial and cable tuning systems up to 1.3 GHz. The RF preamplifier drives the 17-bit main divider enabling a step size equal to the comparison frequency, for an input frequency up to 1.3 GHz covering the complete terrestrial frequency range. A fixed divide-by-two additional prescaler c.
