The SP5730 is a single chip frequency synthesizer designed for tuning systems up to 1.3GHz and is optimized for digital terrestrial applications. The RF preamplifier interfaces directly with the RF programmable divider, which is of MN1A construction so giving a step size equal to the loop comparison frequency and no RF prescaler phase noise degradation over the full RF operating range. The comparison frequency can be obtained either from an on-chip crystal controlled oscillator, or from an external source. The oscillator frequency, fREF, or phase comparator frequency, fCOMP, can be switched to the REF/COMP output providing a reference for a second frequency synthesizer. The synthesizer is controlled via an I2C bus and is fast mode compliant with 3.3V and 5V logic levels.
