SP5658F, Frequency Synthesizer, 2.7GHz, 3-Wire Bus Control ,SO-14

The SP5658F is a high-performance, single-chip frequency synthesizer specifically designed for tuning systems up to 2.7GHz. With a 3-wire bus control interface, it provides accurate and stable frequency generation, making it ideal for communication systems, SAT, TV, VCR, and cable tuning applications. The device includes two selectable prescaler options, enabling it to divide input frequencies up to 2GHz, which makes it highly adaptable for diverse application requirements.

The SP5658F features low phase noise, essential for high-clarity signal generation, and integrates a charge pump disable function for power-efficient operation. It is also equipped with a varactor line disable and an "in-lock" flag for additional control and status monitoring. Housed in a compact SMD package, the SP5658F ensures reliable operation with ESD protection compliant with MIL–STD 883 TM 3015, providing robust performance even in demanding environments.
