FS6128-04G-XTP

The FS6128-04G-XTP from ON Semiconductor is a monolithic CMOS clock generator IC designed for digital video and audio systems. It features a phase-locked loop (PLL) device that synthesizes output clock frequencies from a crystal oscillator or external reference clock. The integrated tunable voltage-controlled crystal oscillator (VCXO) allows for precise system frequency tuning, making it suitable for applications with frequency matching requirements like digital satellite receivers.

This IC operates at a 3.3V supply voltage and offers a very low phase noise PLL. It is designed to be used with 'pullable' 14pF crystals, eliminating the need for external padding capacitors. The output clock frequency is 27MHz, derived from a nominal 13.5MHz input crystal. The device is packaged in an 8-pin SOIC with a small circuit board footprint.

The FS6128-04G-XTP is typically used for generating MPEG-2 decoder clocks. Its high-resolution PLL and post-divider generate the output clock, which is ratiometrically derived from the VCXO frequency. Locking the CLK frequency to other system references can help eliminate artifacts in video systems and reduce electromagnetic interference (EMI).

Key specifications include a 3V to 3.6V operating voltage range, a 0°C to 70°C operating temperature, and a 1:1 ratio. The component is surface mountable and comes in an 8-SOIC package.
