SP5730 General Description

The SP5730 is a single chip frequency synthesiser designed for tuning systems up to 1·3GHz and is optimised for digital terrestrial applications. The RF preamplifier interfaces direct with the RF programmable divider, which is of MN1A construction so giving a step size equal to the loop comparison frequency and no prescaler phase noise degradation over the full RF operating range. The comparison frequency is obtained either from an on-chip crystal controlled oscillator, or from an external source. The oscillator frequency, f_REF, or phase comparator frequency, f_COMP, can be switched to the REF/ COMP output providing a reference for a second frequency synthesiser. The synthesiser is controlled via an 1²C bus and is fast mode compliant. It can be hard wired to respond to one of four addresses to enable two or more synthesisers to be used on a common bus. The device contains four switching ports P0 - P3.
