The 844003AKI-04LF is a differential output LVDS synthesizer designed for generating Ethernet reference clock frequencies. It supports output frequencies of 625MHz, 622.08MHz, 312.5MHz, 250MHz, 156.25MHz, 125MHz, and 100MHz, selectable via four frequency select pins. The device features three LVDS outputs across two banks, with Bank A providing one output pair and Bank B offering two output pairs, each independently configurable. The synthesizer utilizes advanced low phase noise VCO technology, achieving a typical rms phase jitter of 0.50ps at 125MHz, which meets Ethernet jitter specifications. It operates within a temperature range of -40¬8C to 85¬8C and is packaged in a 32-pin VFQFN format. The product is lead-free and compliant with RoHS standards.
