Renesas Electronics Corporation Clock Generators, PLLs, Frequency Synthesizers ICS487G-25LF

The ICS487G-25LF is a quad Phase Locked Loop (PLL) clock generator designed for digital television (DTV) applications. It generates five high-frequency clock outputs and is capable of replacing multiple crystals and oscillators, utilizing a 27 MHz crystal or clock input. The device features zero ppm frequency synthesis error, ensuring that audio clocks remain synchronized with video outputs. Packaged in a 16-pin TSSOP format, the ICS487G-25LF operates at a voltage of 3.3 V and employs an advanced low power CMOS process. The output frequencies include 48 MHz, 20 MHz, 24.576 MHz, and 33 MHz, with an audio clock output determined by select pins. The device requires external capacitors for optimal performance and includes features for power-down functionality. Engineers considering this product should note its suitability for applications requiring precise clock generation with minimal frequency error, particularly in DTV systems.
