FS7140-02G-XTD Description

The FS7140-02G-XTD from onsemi is a PLL Clock Generator designed for high-performance timing applications. This obsolete but robust IC integrates a phase-locked loop (PLL) to generate stable clock signals from an external crystal input, supporting frequencies up to 400MHz. It operates within a 3V to 3.6V supply range and delivers CMOS and PECL outputs, making it suitable for mixed-signal systems. The device features a 2:1 input-to-output ratio and includes divider/multiplier functionality for flexible clock synthesis. Packaged in a 16SSOP tube, it is RoHS3 compliant and rated for 0°C to 70°C operation, ensuring reliability in industrial environments.
