Renesas Electronics Corporation Integrated Circuits (ICs) - Clock-Timing - Clock Generators, PLLs, Frequency Synthesizers 844003BG-01LF

The 844003BG-01LF is a frequency synthesizer IC designed to generate Ethernet reference clock frequencies with a maximum output frequency of 625MHz. It features three differential LVDS output pairs distributed across two output banks, allowing for independent frequency selection. The device can utilize either a 19.53125MHz or 25MHz crystal and supports output frequencies of 625MHz, 312.5MHz, 156.25MHz, and 125MHz, configurable via four frequency select pins. This synthesizer employs IDT,Äôs third-generation low phase noise VCO technology, achieving a typical rms phase jitter of 0.56ps at 156.25MHz, which meets Ethernet jitter requirements. The operating temperature range is from 0¬8C to 70¬8C, and it is packaged in a compact 24-pin TSSOP format. The product is RoHS compliant and available in lead-free configurations.
